07c42cb32d sw_engine: gradient transformation combined with the shape transformation 
The gradient transformation has to be included in the last step
of gradient preparation (and combined with a shape transformation).

362d2dfd0f sw_engine: refactoring 
The rasterization region was rearranged in the case of fastTrack,
but its validation and boundaries weren't check, causing segf in some
cases. Fixed.

babb10b7f3 sw_engine: rasterization region edited in the case of fast tracking 
Since no antialiasing is applied for the fastTracking cases,
the shape's rasterization region needs to be edited. To establish
the rastered bbox, the rounding is performed before the bbox corners
are casted to the SwCoords.

003f53376e jpg loader: support static jpeg loader using richgel999 
Adds an alternative static jpg loader.

The jpg loader copied the jpeg decoding implementation from this open-source
repo: https://github.com/richgel999/jpeg-compressor
That opensource has the public-domain license, it doesn't have any restriction
of the copy.

note: jpgd.cpp is modified version (changed decompress_jpeg_image_from_stream)
for returning BGRA

5be27a151e capi: ++missing const in capis. 
Non-changeable apis should keep the const parameter so that
user knows the api won't change the internal data.

Thanksfully, we didn't release the capis, we can change it.

Yes, now we have standard apis for getting class types,
don't need to hack it anymore.

78d85d714a common: Introduce class type identifier apis. 
This identifier is useful when user identify the instance type in runtime.

ThorVG basically don't prefer to dynamic_cast() nor typeid(),
it compiles with -fno-rtti option for the optimial size.

Here is an example for the simple usage.

if (paint->identifier() == Shape::identifier())
  auto shape = static_cast<Shape*>(paint);

d3ba000d80 png_loader meson: Remove dependency check using find_library()

2e6715ba41 loader png: support static png loader 
Copied only necessary decoding functions from the lodepng opensource.
See: https://lodev.org/lodepng/

additional changes:
- disabled crc for the optimal size.
- converted the format bgr -> rgb for our png example.

Still we don't have a concrete idea for the image formats,
We should fix the converting methods between bgra <-> rgba.

e5196d610d svg_loader XMLParser: Refacotring simpleXmlParse method 
1.
Remove macro function. The existing macro function
was doing meaningless nested `return false`.

2.
Extract the logic to find the type as a function.

3.
The SimpleXMLType::Error case is not actually used,
and in case of invalid XML, Do 'return false' immediately.
