When a shader is loaded, by default, several locations are tried to be set automatically.

RENAMED: GetCodepoints() -> LoadCodepoints(), now codepoint array data is loaded dynamically instead of reusing a limited static buffer.
ADDED: UnloadCodepoints() to safely free loaded codepoints
RENAMED: GetNextCodepoint() -> GetCodepoint()

Moved outside BeginDrawing()/EndDrawing() to illustrate drawing is happening to an external texture (not screen)

Added missing null terminator when adding characters to the string, otherwise garbage values are read (often zeros which are equal to '\0', but not every time).

This error results in random characters appearing in the text box every one in a while:
```
asdfg??? ll??
```
It is corrected with the proposed fix.

This problem was observed by my student, Gonzalo Rivera Lazo.

RENAMED: InitAudioStream() -> LoadAudioStream()
RENAMED: CloseAudioStream() -> UnloadAudioStream()

- RENAMED: RayHitInfo to RayCollision
- RENAMED/REDESIGNED: Multiple Ray collision functions to be more consistent and return RayCollision data -WIP-

Added a simple cube with vertex colors for testing both.

Renamed for consistency with other function in raylib.

* Hotfix for glitchy camera

Super small fix that was causing the camera to glitch every x amount of seconds/pixels. Works much better now, 3/4 lines changed.

* fixed dumb visual studio formatting problems

* Typo fix

Changed "bsasic" to "basic" in the comments.

* Added pixel-perfect camera example

Added pixel-perfect camera example, both the .c file and the cover .png image. The example works with any resolution you want, as long as the ratio stays the same
(ex. 16:9, 4:3) ecc.

* Fixed Typecasts

Fixed compiler errors (implicit conversions)

* Precomputed rectangles, time-based movement and whitespace fix

Moved the source and destination rectangles for the renderTexture into their own variables, modified the animation to be time-based instead of frame-based, fixed the bug with whitespaces.

* Fixed spacing and added more consistency with sinf() and cosf()

* Fixed *= operator spacing

* Added support for additional mouse buttons

* Renamed mouse button enum

* Added an example for raylib OpenGL interop.

* Removed C99 variable-length array to fix MSVC errors

* Moved the opengl interop example from shaders to others.

* Fix olds directories used and windows/linux portability

* Fix windows/linux portability
