SetWindowTitle()
GetExtension()

Now it works great with reviewed maths

Some other tweaks...

Now it should be coherent with OpenGL math standards

Exposed some raymath useful functions to raylib API

Consistent with similar functions in raymath

...to avoid possible conflicting symbols

If we compile with c99 without gnu extensions (gnu99) we need this
define, to have CLOCK_MONOTONIC and similar macros available

Comments to create transparent framebuffer on RPI,
when activate you see though full screen window the console below!

useful when using FLAG_WINDOW_RESIZABLE.

enum LogType could require some revision...

Replaced old GetExtension() function
Make IsFileExtension() public to the API

Moved to custom example, now raylib only supports simulated VR
rendering.
Oculus code was too device dependant... waiting for OpenXR.

It seems Sleep() behaves weird on my computer, disabled by default
returning to the busy wait loop... also re-implemented DrawFPS() to
avoid frame blitting...

- SetWindowPosition(int x, int y);
- SetWindowMonitor(int monitor);

Working in modules configuration flags...

Only DESKTOP platforms (Windows, Linus, OSX)

Preparing for next version... still some work left... :P

Now program is halted (OS signal call) for required amount of time every
frame, so CPU usage drops to zero, instead of using a busy wait loop.

...instead of keep polling
