Why does the grid in this SVG not fill the entire 256x256 space? No matter what size I change it to, about 15% of the grid is cut off, which appears to me to be arbitrary in the context of my code.
<svg width="256" height="256" xmlns="http://www.w3.org/2000/svg"

<pattern id="grid" width="18.75" height="18.75" patternUnits="userSpaceOnUse">

</pattern>
<rect id="gridRect" width="100%" height="100%" fill="url(#grid)" />
<filter id="gridify" width="100%" height="100%" filterUnits = "userSpaceOnUse">
<feImage result="sourceTwo" xlink:href="#gridRect" />
<feComposite in="SourceGraphic" in2="sourceTwo" operator="in"/>
</filter>
</defs>
<g filter="url(#gridify)" >

The SVG specification defaults filters to being 10% larger than the filtered object by default.
If ‘x’ or ‘y’ is not specified, the effect is as if a value of -10% were specified.
If ‘width’ or ‘height’ is not specified, the effect is as if a value of 120% were specified.
I imagine that's to stop lots of questions along the lines of "why is my Gaussian blur based drop-shadow filter cut off?"
So, looks like all I needed to do to fix it was add an x="0" and a y="0" to the filter. I don't understand why it is necessary though, as it does not make sense that it would default to "-15%".

I am trying to make mirrored pattern, but when I add displacement filter, it seems it only works on first and fourth quandrant. Am I overlooking some beginner mistake or is this behavior expected?

In your filter I've added xChannelSelector="R" for the feDisplacementMap. I'm using R for red since your shapes are red.
<filter id="noise" x="0%" y="0%" width="100%" height="100%">
<feTurbulence baseFrequency="0.02" numOctaves="3" result="noise" seed="3" />

Also I would have applied the filter to the <rect> inside <symbol> instead of applying it to the group.
You're just missing an xChannelSelector or yChannelSelector - one of which is required.
(Update - as you mention in the comment, when you leave this out, it defaults to using the alpha channel in both X and Y - so it will shift everything up and down the top/left bottom/right diagonal axis - so solid color diagonal lines with this orientation will only show distortions at their starting and finishing edges).
If you're not going to process the feTurbulence in some way after you generate it, then any one of the channels (RGBA) works as a displacement source - since Perlin noise is equally noisy in all four channels.
(You don't need to use the R channel because your shapes are red - that's backwards - the channel selector applies to your noise input, not your the shape you want to apply it to.)

I'm trying to apply a texture to an image
Original
Texture
Result (made with PHP GD)
But with SVG, the closest I got is this result
<svg preserveAspectRatio="none" width="500" height="500" viewBox="0 0 500 500">
<defs>
<filter id="texture">
<feImage href="https://i.imgur.com/pjWcnJs.jpg" result="texture-img"/>
<feBlend in="SourceGraphic" in2="texture-img" mode="multiply"/>
</filter>
</defs>
<g>
<g filter="url(#texture)">
<image x="0" y="0" href="https://i.imgur.com/oVEdsQt.png" opacity="1" width="500" height="500" />
</g>
</g>
</svg>
fiddle
Is there another way which won't texturize transparent pixels?
I found a solution which is to pass the texture through a composite filter which would crop it to the source image
<svg preserveAspectRatio="none" width="500" height="500" viewBox="0 0 500 500">
<defs>
<filter id="texture">
<feImage href="https://i.imgur.com/pjWcnJs.jpg" result="texture-img"/>
<feComposite in2="SourceGraphic" operator="in" in="texture-img" result="composite"/>
<feBlend in="SourceGraphic" in2="composite" mode="multiply"/>
</filter>
</defs>
<g>
<g filter="url(#texture)">
<image x="0" y="0" href="https://i.imgur.com/oVEdsQt.png" opacity="1" width="500" height="500" />
</g>
</g>
</svg>
To tile the texture, I used feTile like this
<svg preserveAspectRatio="none" width="500" height="500" viewBox="0 0 500 500">
<defs>
<filter id="texture" x="0" y="0" width="100%" height="100%">
<feImage href="https://i.imgur.com/gWH7NLm.jpg" result="texture-img" width="256" height="256"/>
<feTile in="texture-img" x="0" y="0" width="100%" height="100%" result="tile" ></feTile>
<feComposite in2="SourceGraphic" operator="in" in="tile" result="composite"/>
<feBlend in="SourceGraphic" in2="composite" mode="multiply"/>
</filter>
</defs>
<g>
<g filter="url(#texture)">
<image x="0" y="0" href="https://i.imgur.com/oVEdsQt.png" opacity="1" width="500" height="500" />

I got the idea by checking how inkscape applies material textures
I have the following SVG code which draws many squares:
<svg width="100%" height="100%" viewBox="0,0,100%,100%" xmlns="http://www.w3.org/2000/svg">
<defs>
<pattern id="smallGrid" width="1.388888888888889%" height="5%" patternUnits="userSpaceOnUse">
<path fill="#2e99e5" d="M0 0h960v960H0z" stroke="gray" stroke-width="0.5"/>
</pattern>
<pattern id="grid" width="8.333333333333333%" height="50%" patternUnits="userSpaceOnUse">
<rect width="100%" height="100%" fill="url(#smallGrid)"/>
<path fill="none" d="M0 0h960v960H0z" stroke="gray" stroke-width="2" />
</pattern>
</defs>
<rect width="100%" height="100%" fill="url(#grid)" />
</svg>
Is there a way to select the first 3 <path fill="#2e99e5" d="M0 0h960v960H0z" stroke="gray" stroke-width="0.5"/>
and change the color?
I'm trying to use a external symbol with a filter. Unfortunately it looks like the browsers don't support this feature.
Am I declaring it wrong or hasn't it been implemented?
Example page: http://www.lisa.ink/svg/
Chrome only shows the last svg
Firefox shows the first and second svg as expected
Safari only shows the last svg as expected
1. Using external symbol with only a fragment identifier
html:
<svg>
<use xlink:href="/svg/rect.svg#rect" />
</svg>
external svg:
<svg>
<defs>
<filter id="hueRotate">
<feColorMatrix in="SourceGraphic" type="hueRotate" values="90" result="A"/>
</filter>
<symbol id="rect" viewBox="0 0 640 550">
<rect x="0" y="0" width="200" height="200" fill="red" filter="url(#hueRotate)" />
</symbol>
</defs>
</svg>
2. Using a external symbol with a full IRI
html:
<svg xmlns="http://www.w3.org/2000/svg">
<use xlink:href="/svg/rect.svg#rectWithFullUrl" />
</svg>
external svg:
<svg>
<defs>
<filter id="hueRotate">
<feColorMatrix in="SourceGraphic" type="hueRotate" values="90" result="A"/>
</filter>
<symbol id="rectWithFullUrl" viewBox="0 0 640 550">
<rect x="0" y="0" width="200" height="200" fill="red" filter="url(/svg/rect.svg#hueRotate)" />
</symbol>
</defs>
</svg>
3. Using a external symbol with local
html:
<svg xmlns="http://www.w3.org/2000/svg">
<use xlink:href="/svg/rect.svg#rectWithMissingFilter" />
</svg>
<svg xmlns="http://www.w3.org/2000/svg">
<defs>
<filter id="missingHueRotate">
<feColorMatrix in="SourceGraphic" type="hueRotate" values="90" result="A"/>
</filter>
</defs>
</svg>
external svg:
<svg xmlns="http://www.w3.org/2000/svg">
<defs>
<symbol id="rectWithMissingFilter" viewBox="0 0 640 550">
<rect x="0" y="0" width="200" height="200" fill="red" filter="url(#missingHueRotate)" />
</symbol>
</def>

I have an svg shape which uses a pattern. I want the pattern to NOT scale when i scale the shape.
Here's a fiddle with a minimal example, the bigger circle should show the pattern like the smaller one:
http://jsfiddle.net/cTMrQ/6/
<svg style="position: absolute" width="100%" height="100%" version="1.1" baseProfile="full" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:ev="http://www.w3.org/2001/xml-events">
<defs>
<pattern id="checkerPattern" patternUnits="userSpaceOnUse" x="0" y="0" width="4" height="4">
<image x="0" y="0" xlink:href="http://inwonderland.at/new/lines.png" width="4" height="4" />
</pattern>
<circle fill="url(#checkerPattern)" id="c" cx="50" cy="50" r="50" />
</defs>
<use x="100" y="100" xlink:href="#c" />
<use x="200" y="100" xlink:href="#c" transform="scale(2)" />
</svg>
In the end the shape will be a complex path and the image in the pattern will be a scan of a piece of paper, so just drawing a bigger circle instead of scaling it won't work.
Update
To clarify what i want, here are two images:
this is what it looks like, no matter what i try, when i scale the shape:
http://inwonderland.at/new/ihave.png
this is what i want:
http://inwonderland.at/new/iwant.png
i want the background image (bitmap image) to always have its natural size.
You can't get what you want using a pattern, the transform always happens after the fill, and you can't just move the pattern fill into a wrapper either. My suggestion is to use a filter and apply the filter on a wrapper - like so:
<svg style="position: absolute" width="100%" height="100%" version="1.1" baseProfile="full" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:ev="http://www.w3.org/2001/xml-events">
<defs>
<circle fill="url(#checkerPattern)" id="c1" cx="50" cy="50" r="50" />
<filter id="linepattern" x="0%" y="0%" height="100%" width="100%">
<feImage xlink:href="http://inwonderland.at/new/lines.png" result="pattern" width="4" height="4"/>
<feTile/>
<feComposite operator="in" in2="SourceGraphic"/>
</filter>
</defs>
<use filter="url(#linepattern)" x="100" y="100" xlink:href="#c1" />
<use filter="url(#linepattern)" x="200" y="100" xlink:href="#c1" transform="scale(2)" />
<g filter="url(#linepattern)">
<use x="50" y="100" xlink:href="#c1" transform="scale(2)" />
</g>
</svg>
Using viewport
1:1 no zoom
<svg width="800" height="400" viewBox="0 0 800 400">
2:1 zoom double size
<svg width="800" height="400" viewBox="0 0 400 200">
The following elements can use the viewBox attribute
<svg>
<symbol>
<image>
<marker>
<pattern>
<view>
viewbox is fully animatable; and you can zoom into any center point.
<animate attributeName="viewBox" begin="1s" dur="1s"
values="0 0 600 400; 250 180 300 200" fill="freeze" />
Transform a parent tag
Yes an SVG can be a child element but more commonly shapes made with multible tags are placed inside a group tag.
Transform scale can be used with tags which are parents IE the group tag.
<g transform="scale(1.5)">
/* draw your shape inside the g tag */
<use x="100" y="100" xlink:href="#c" />
<use x="200" y="100" xlink:href="#c" />
</g>
So using your above example scale the shape in a parent tag.
Update
To scale image but not patterns in other words move patterns, or icons, on background image that scales.
<g transform="scale(2)">
/* draw your shape inside the g tag */
<use x="100" y="100" xlink:href="#c" transform="scale(.5)" />
<use x="200" y="100" xlink:href="#c" transform="scale(.5)"/>
</g>
Update full svg
I had to move things around a bit, One full size, (lets call it a map), with an overlay of 1 half size map in the upper left corner. setting the full screen to render between 0 and max of 600. Setting a viewport the same but with the width set to 300 scales it down. I do need to double the radius for this example of scaling.
<svg viewBox="0 0 600 600" style="position: absolute" width="100%" height="100%" version="1.1" baseProfile="full"
xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:ev="http://www.w3.org/2001/xml-events">

</pattern>
<circle fill="url(#checkerPattern)" id="c" cx="50" cy="50" r="50" />
<circle fill="url(#checkerPattern)" id="c2" cx="50" cy="50" r="100" />
</defs>
<use x="100" y="100" xlink:href="#c" transform="scale(.5)"/>
<use x="200" y="100" xlink:href="#c" transform="scale(1)"/>
<rect width="600" height="600" style="fill: none; stroke: black;" />
<svg viewBox="0 0 600 600" width="300" height="300" x="300">
<use x="100" y="100" xlink:href="#c2" transform="scale(.5)"/>
<use x="200" y="100" xlink:href="#c2" transform="scale(1)"/>
<rect width="600" height="600" style="fill: none; stroke: black;" />
</svg>
</svg>
This example is scaled using the same circle pattern. The radius does not need to be changed here because the location is not in the tag being scaled. I'm making use of svg tags here but other tags can be used.
