* This snippet is a crude and ugly svg compression script, intended to be used on stuffs
* that require extremely low file space. Using an asci string data, it converts it to an
* equivalent SVG format image object.
*
*
* SVG TYPES
* 000: rectangle - rect = x, y, width, height, [stroke, stroke-width, fill, opacity]
* 001: ellipse - ellipse = cx, cy, rx, ry, [stroke, stroke-width, fill, opacity]
* 010: polyline - polyline = [stroke, stroke-width, fill, opacity], point
* 011: polygon - polygon = [stroke, stroke-width, fill, opacity], point
* 100: path - path = [stroke, stroke-width, fill, opacity], d
* 101: def - def = [0, 0, 0, type gradient],
*
* SVG ATTRIBUTES
* 0000: bit flags corresponding to the following [stroke, stroke-width, fill, opacity]
*
* DATA PARSING
* [0], First byte will contain the svg type and the flag attributes
* [nth], Succeeding bytes will correspond to the SVG attributes depending on the order
* [~], A tilde will serve as a delimeter in case of multiple SVG type present
*
* COLOR RANGE
* @see Vectori.color64 this is a Base4 color system
*
* PATH SVG TYPE SPECIAL HANDLING
* Path has a special case it cannot have a coordinate within 81-90 range. this will be
* reserved for the following code: 81-M, 82-L, 83-H, 84-V, 85-C, 86-S, 87-Q, 88-T, 89-A,
* 90-Z, 91-Toggle from upper or lower case.
*
* NOTE
* - The number range for all Integer is 0-93 because I like it that way.
* - Colors are limted to 0,6,a,f values because I dont have enough digits to represent
* the entire spectrum.
* - The svg object has a fixed height and width of 900
* - All number coordinates are multiplied by 10
*
* SUPPORTED BROWSERS
* IE9+, Chrome, Firefox
