* Add options to zig compile options

Support for compiling with raygui, raymath, and physac.
Also outputs the required headers.

Raygui should be located `../raygui` relative to the repo root
Physac should be located `../physac` relative to the repo root

This behavior matches options in the Makefile

* Move Options struct

* Remove physac, explicit raymath, always copy rlgl.h and raymath.h

* Remove unused options from build.zig

* Add srcdir as include path for raygui.h

* Continuation of support for ES3/WebGL2

* GetTouchPointState()

* Amends to the WebGL2 PR

Only PNG supported for now

I Added Analog Stick Support to the rcamera module, However this code only allowed for 4 Directions of Movement, This Changed adds the full range of Movement to the Right Analog Stick.

The color macros don't work properly in C++98, because they require
aggregate initialzation, which is a C++11 feature. So, explicitly state
how to fix this issue, instead of letting the compiler give a more vague
error message like:

main.cpp:8:23: error: expected '(' for function-style cast or type construction
      ClearBackground(BLACK);
                      ^~~~~
/opt/homebrew/Cellar/raylib/4.5.0/include/raylib.h:179:35: note: expanded from macro 'BLACK'
 #define BLACK      CLITERAL(Color){ 0, 0, 0, 255 }         // Black

NOTE: Don't use this check with MSVC because by default, it reports
199711L  regardless of any C++ version passed on command line
Only passing `/Zc:__cplusplus` will make MSVC set this correctly

Just added the required flags to request the OpenGL ES 3.0 context but it has not been tested...

* added cross compilation options for DRM

* fixed identation

* Added ImageRotate

* Quick rename of the example

* Update ImageRotate by changing doubles to floats and checking code convention

* Update API

* Add GenImageGradientSquare to allow square gradients

* Fix GenImageGradientSquare and add to textures_image_generation example

* Remove params from GenImageGradientSquare

* Replaced GenImageGradientH and GenImageGradientV with GenImageLinearGradient

* renamed GenImageLinearGradient to GenImageGradientLinear
