Function provisional renaming... that's not the end of this issue...

When capturing framebuffer, if some element with transparency has been drawn, it retrieves that data... it could be a bit annoying in some situations because we could expect color compositing with background color... It depends on the situation and our needs... but most of the time we don't want that transparency on screenshots.

Following raylib notation rules

This specific change could be very annoying for people already using FLAG_MSAA_4X_HINT, their programs will compile correctly but window won't be shown...

Planning to promote raudio module as a simple and easy-to-use front-end for the amazing mini_al library, so the name change.

Name comes from raylib-audio but in spanish it also remembers to word "raudo", meaning  "very fast", an analogy that fits perfectly to the usefulness and performance of the library!

Consequently, raylib version has been bumped to 2.4-dev.

- Unsigned int not supported on OpenGL ES 2.0 -> Removed
- Reorganized enum -> Removed BOOL (not uniformType)
- Support sample2D uniform type

This reverts commit 1fe6d9fc06.

Because upstream GLFW now contains a fix.

glfw/glfw@5595fa3ae6 implements a proper fix for the macOS Mojave
problem of OpenGL windows not being rendered until moved or manually
updated.

Pull in the current master and rebase the three patches we have on top:
- two commits we have for reuse of the GLFW CMake build system for Wayland
It hasn't yet to be acknowledged upstream.
- one commit removing #include <windows.h> in glfw3native.h to avoid
duplicate declarations.

Fixes #655 and #665.

Specific textures generation code is quite redundant and not flexible for the user, I'm trying to figure out some easy way to allow raylib users to do the same without needing those functions (very specific and shader dependant). RenderTexture loading and Cubemap textures support must be improved.

Actually, that function should be redesigned...

Considering chars inputs come in UTF8 form!

Same functionality could be achieved using FLAGS... but also considering removing raylib logo animation...

Decided to allow user to provide values directly instead of requiring a Vector2 struct, probably more confortable to use.

 - SetMousePosition()
 - SetMouseOffset()
 - SetMouseScale()

- SetMouseScale changed to take in a Vector2.
- Added mouseOffset global which is used in mouse read functions.

- Didn't set X and Y values correctly.

- Changed mouseScale to Vector2.
- Added SetMouseOffset to change XY of mouseScale.
