* Added rudimentary SVG support. Added 2 functions ImageLoadSvg and ImageLoadSvgWithSize. * Added an example on how to use ImageLoadSvgWithSize and adjusted Makefiles accordingly. * Added actual correct example file. * Reviewed the code to keep the raylib coding conventions in mind. Moved the LoadImageSvg() code into LoadImage() guarded by SUPPORT_FILEFORMAT_SVG. Renamed LoadImageSvgWithSize() to LoadImageSvg(). Added a LoadImageSvgFromString() function to parse the loaded SVG into an actual image. This does the bulk of the work. * Fixed typo. --------- Co-authored-by: Ray <raysan5@gmail.com>
