Large user coordinates in SVG - svg

I cannot get coordinate systems with large values to work. The renderer seems to just treat them as pixel values. For example:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns:ev="http://www.w3.org/2001/xml-events"
width="100%" height="100%"
viewBox="0 0 50000 50000"
>
<circle cx="25000" cy="25000" r="10px" fill="red" />
</svg>
This uses a user coordinate system of a 50000 x 50000 square in the center of which should be a red dot, but no dot appears.

Why will browsers not display my SVG polygon?

I have created an SVG file to display an icon for an open folder.
It consists of a rectangle for the tab and a rectangle for the backleaf of the folder, with the open leaf represented by a polygon.
Image editors display the intended result, but browsers seem to ignore the polygon.
what am I missing?
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg id="folder_icon" xmlns="http://www.w3.org/2000/svg"
width="90" height="60" viewbox="0 0 90 60" preserveAspectRatio="xMidYMid slice"
xmlns:xlink="http://www.w3.org/1999/xlink">
<g width="50%" height="80%">
<g id="g3" fill="#ffee77" stroke="#bb7711" stroke-width="2px" opacity="0.7">
<g id="g2">
<rect x="16%" y="1%" rx="6%" ry="6%" width="30%" height="30%" />
<rect x="1%" y="16%" rx="0%" ry="0%" width="84%" height="82%" />
<polygon points="17% 20%, 90% 20%, 75% 59%, 1% 59%" />
</g>
</g>
</g>
</svg>
The same file converted to a PNG is displayed as intended, but I would prefer to use the scalable graphic.

Masking an SVGPattern

fiIs it possible to Mask an SVGPattern?
I've made the following SVG, but I can't get the mask to work.
Or should I be using clipPath?
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="160px" height="600px" viewBox="0 0 160 600" version="1.1"
xmlns="http://www.w3.org/2000/svg">
<defs>
<pattern id="circlePattern" patternUnits="userSpaceOnUse"
x="0" y="0" width="10" height="10"
viewBox="0 0 10 10" fill="blue" >
<circle cx='4' cy='4' r='4'/>
</pattern>
<clipPath id="clipPath" maskUnits="userSpaceOnUse">
<rect x="0" y="0" width="200" height="100" fill="white" />
</clipPath>
</defs>
<!-- Outline the drawing area in blue -->
<g id="box">
<rect fill="url(#circlePattern)" width="160" height="600" clip-path="url(#clipPath)"/>
</g>
</svg>
UPDATE: (I would like to use this complex path)
I can't seem to use this path to create the mask/clipPath
<path style="fill:#FFFFFF;" d="M9.35,37.5c4.1,2.467,8.566,3.7,13.4,3.7

Your mask rect has no fill specified so it will use the default which is black i.e. i.e. rgba(0, 0, 0, 1). So the luminance of the mask is 0 everywhere and you see nothing.
If you change the fill on the mask <rect> to fill="white" you'll see the mask act as a clip which would seem to be what you're looking for. Other colours like "orange" or "blue" as they have a luminance which is neither 0 nor 1 will give you an intermediate effect.
clipPaths clip a shape to a boundary. Masks generally modify colours, you can use them to clip by having a white mask but if all you want is to clip something then a clipPath is faster.
clipPaths and masks can contain any graphics element including a path.

SVG Resize Image out of aspect ratio

I'm trying to figure out how to take a complex SVG file and easily resize it to anything id like. Say I want a 100x100 SVG image to be 5x30 I'd like it to resize to that with out any cropping.
I want to do this using only the SVG document or by embedding it into another SVG file. I'm having a lot of trouble achieving this.
For Example:
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" contentScriptType="text/ecmascript" zoomAndPan="magnify" contentStyleType="text/css" viewBox="0 0 100 100" preserveAspectRatio="xMidYMid meet" version="1.0">
<image x="0" y="0" width="516.3034" xlink:href="http://upload.wikimedia.org/wikipedia/commons/e/e5/Tux_chico.svg" xlink:type="simple" xlink:actuate="onLoad" height="777.2853" preserveAspectRatio="xMidYMid meet" xlink:show="embed" />
</svg>
This is only cropping the image when what I wish to accomplish is the embedded image gets shrunk to fit inside the viewbox.

Use percentage for the image element:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" zoomAndPan="magnify" viewBox="0 0 100 100" preserveAspectRatio="xMidYMid meet">
<image width="100%" height="100%" xlink:href="http://upload.wikimedia.org/wikipedia/commons/e/e5/Tux_chico.svg" preserveAspectRatio="xMidYMid meet">
</svg>
Or use the viewBox coordinate system:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" zoomAndPan="magnify" viewBox="0 0 100 100" preserveAspectRatio="xMidYMid meet">
<image width="100" height="100" xlink:href="http://upload.wikimedia.org/wikipedia/commons/e/e5/Tux_chico.svg" preserveAspectRatio="xMidYMid meet" />
</svg>
These two ways may differ slightly if the viewBox aspect ratio doesn't match the viewport since percentages are based on the viewport size. If you don't care about the image aspect ratio you can stretch the image to fit the given size by using preserveAspectRatio="none".

the SVG icons overlap. How can I modify these to have an offset between two icons?
For instance, the one similar to http://dbushell.com/demos/css-sprites/sprite.svg

Try to replace the 2nd M command to m command.
"M" means absolute position, "m" means relative position.

why is text always centered to canvas

When loading a SVG and rendering it to the canvas, the text contained in the path group is always centered. In the example below the text should be placed in the upper left corner.

JS:
fabric.loadSVGFromURL(uri, function (svg, options) {
var group = new fabric.PathGroup(svg, options);
canvas.add(group);
});
Any rect, circle etc. within the pathgroup would be displayed as expected. So why is my text not displayed properly?

I haven't used fabric.js, but you're probably missing the x and y attributes. Also, add text-anchor="start" so it's easier to position:
<text transform="matrix(1 0 0 1 7.5107 14.2222)" font-family="Arial" font-size="12" text-anchor="start" x="0" y="0">Text in the corner</text>
