When using <use> node, do atrribute copy.
At that time, when target(url) is polygon or polyline,
points array is not copied, causing a problem in output.
So, add missing array copy.
Supports case of using style attribute for defined <clipPath>.
In SVG, <clipPath> can be used as a "clipPath" attribute or a style "clip-path".
This patch only supports "clip-path" of style is declared.
The remaining features will be added later.
[Example SVG case]
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
viewBox="0 0 64 64" enable-background="new 0 0 64 64" xml:space="preserve">
<defs>
<clipPath id="clipPath">
<rect x="15" y="15" width="40" height="40" fill="#F00" />
<circle cx="20" cy="20" r="10" fill="#F00" />
</clipPath>
</defs>
<circle cx="25" cy="25" r="20"
style="fill: #0000ff; clip-path: url(#clipPath); " />
</svg>
we should avoid code insertion during file dependencies,
such as #include "xxx.h" which has implementations.
This could increase binary size, we can avoid it as possible.
Current patch improves binary size like this:
From: file(2059008) = text(120360) data(8096) bss(80) dec(128536)
To : file(1921832) = text(118429) data(7872) bss(56) dec(126357)
More additional patches will come in to optmize binary size.
When path ends with 'z' or 'Z' command, if 'm' comes as next command,
the current point is incorrectly referenced.
Since 'Z', 'z' means to close the path,
so, Save point and reuse it when 'M' or 'm' is called.
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.
Mask and clippath TAG are not supported yet.
If this TAG is used, the Child TAG declared with this TAG may cause problems.
To prevent that, declare them as Unknown types until they are supported. (display=none)
Reverted incorrectly modified code in 3b9bb51321.
The newly created node becomes a child of the parent parameter
and is deleted together when parsing ends.
If there is an empty (unused) <defs /> inside the svg file, this can cause problems.
<defs> node is managed separately in loader->def.
So it doesn't have to be added to loader's list.
vector is designed for c++ syntaxes,
it works properly when c++ memory allocator is applied,
Here svg_loader uses c style structures which allocated using malloc()/calloc().
That brings the memory broken of stl vectors.
So, we replaced it with our customized SvgVector to easily fix it.
remove unnecessary condition.
implementation won't be included multiple times not like headers.
Thus this condition is unnecessary.

picture now affords the memory data as input source so that
user can pass svg data memory directly.

we can't control any threads count that could drop the performance.
remove async() and will come back with fine-tuned threading-pool.
