Changes:
1. New shape->duplicate(Shape) api.
2. New example: testDuplicate
3. Added capi binding for duploicate api
4. Added capi duplication test in testCapi.c
Description:
Added implementation of duplicate api. For now it supports stroke
properties and shape properties (fill color, path) duplication.
TODO:
Implement gradient properties duplication
put missing const parameter and correct set/get naming.
attention, these two apis are changed!
tvg_gradient_color_stops() => tvg_gradient_set_color_stops()
tvg_gradient_spread() = tvg_gradient_set_spread()
* thorVG/example: added thorVG example app to convert svg to png
Rasterazing the svg file and extracting it as a png file.
The png encoder uses the 'lodepng' library.
(https://lodev.org/lodepng/)
Usage:
svg2png [svgFileName] [Resolution] [bgColor]
Examples:
$ svg2png input.svg
$ svg2png input.svg 200x200
$ svg2png input.svg 200x200 ff00ff
* ThorVG/Utils: Change examples to utils
* ThorVG/Utils: Move svg2png from util to src/bin
Renamed the build option for svg2png.

When both <defs> and <svg> gradients are declared,
the update of gradient declared in <svg> is omitted.
Therefore, this patch fixes any missing gradient updates.
When there is a matrix of linear gradient, the applied formula is this.
= T(x - cx, y - cy) x g->transform x T(cx, cy)
This patch has modified this formula to work properly.
In relation to the declaration of rx and ry attribute of rect, the following three cases occur.
rx="10" (or ry="10"
rx="10" ry = "0" (or rx="0" ry = "10")
rx="10" ry = "10"
To cover these case, we check the rx and ry declarations.
tvg canvas must draw retained shapes for every draw call
even though user missed call update() for shapes.
that case canvs must draw shapes without update,
it means drawing them within previous condition.
