* created ImageFromChannel
Adds the possibility to extract a specific channel from an image
* naming convention
* example window height
* removed threshold
* removed alpha channel
* channel example organization
* updated channel example image
Fixed a grammatical error by removing "are" to change `... but some are have multiple purposes ...` to `... but some have multiple purposes ...` in `textures/textures_image_generation`
* 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.

* Add GenImageGradientSquare to allow square gradients
* Fix GenImageGradientSquare and add to textures_image_generation example
* Remove params from GenImageGradientSquare
This adds `ImageDrawCircleLines()` and `ImageDrawCircleLinesV()` to draw outlines of circles, and updates `ImageDrawCircle()` draw a filled circle to match the effect of `DrawCircle()` and `DrawCircleLines()`.
raylib was using `stb_perlin.h` library to generate perlin noise, it seems that recently this library has been flagged as it could be infringing some algorythm patent. For security, it has been removed from raylib.
CONVENTIONS:
- Functions are always self-contained, no function use another raymath function inside, required code is directly re-implemented inside
- Functions input parameters are always received by value
- Functions use always a "result" variable for return
- Functions are always defined inline
- Angles are always in radians (DEG2RAD/RAD2DEG macros provided for convenience)
