This reverts commit 4cd131cf29.

* add base of rlsw.h

* implement state support
Also replace the triangle rasterization functions with macros that generate specific functions for each state of the rendering system.
Also, add the OpenGL definitions in order to add a binding for rlgl.

* branchless float saturation

* apply perspective correction to colors

* impl line clipping and rasterization
+ tweak function names

* impl face culling

* impl color blending

* fixes and tweaks

* add clear buffer bitmasks

* small optimizations / tweaks

* review ndc to screen projection

* avoid to recalculate MVP when its not needed + tweaks

* review the loading and management of textures
to be closer to the OpenGL API

* texture sampling optimization

* review get pixel functions
+ review unorm/float conversion

* add several buffer format support
Several depth and color formats have been added for the framebuffer.

8-bit, 16-bit, and 24-bit formats are now available for depth.

RGB 8-bit (332), RGB 16-bit (565), and RGB 24-bit (888) formats are now available for color.

Alpha support is no longer present for the framebuffer at the moment, but it can easily be restored by adding the formats and reinterpolating the alpha in the areas that do not perform color blending.

Additionally, this commit brings performance improvements.

* tweaks

* impl line width

* impl points + point size

* fix and improve polygon clipping functions

* impl polygone modes

* add some not planned functions
- `glDepthMask`
- `glColorMask`

* framebuffer resizing + handle init failure

* add quick notes about line clipping algorithms used

* start to impl scissor test + review line clipping
The support for the scissor test has been implemented for clearing as well as for triangle clipping.
The implementation for lines and points is still missing.

I also removed the 2D clipping of lines that used the Cohen-Sutherland algorithm, opting instead to always use the Liang-Barsky algorithm in all cases.
This simplifies the implementation, and the 2D version would have caused issues when interpolating vertices in the future if we want to implement additional features.

* adding core_input_actions

action based input API vs direct input, allows remapping of buttons or keys to an action.

* adjusted formatting.

* updates for struct name

and fixed a typo

* gate with OPENGL_11 prototype and definition for rlSetPointSize and rlGetPointSize

* gate with OPENGL_11 prototype and definition for rlSetPointSize and rlGetPointSize

* more coverage for fixing expected texcoords, normals, and colors

* fix guard styling

* fix guard issue, and remove fallback unneccessary else clause (default shader ill work)

* opengl3.3 and es2 need the color array allocated in order to allow for updates later (unlike opengl11)

Now it works! but there is still work to do to support all required features...

I really enjoyed reviewing and redesigning this platform backend!
