* Updated QOI to latest version.

* Enable back QOI support!

* Stray extra space! Should be good now.

Justification: original comment said the following
"TODO: Add other platforms. Remove sudo requirement, i.e. add USER mode."

For the other platforms part, installing is included on unix-like
systems, so for example Windows doesn't have a path where to install
libraries.

Removing the requirement for sudo is also quite contradictory since
we're writing files to directories which require root. Not sure what the
original commiter meant by USER mode.

Added a note for a future improvement

Built files should be put into src/ not into the project root
as it was now on these platforms

* Fixed functions Vector2Angle and Vector3Angle

* typo

* Unrolled everything.

Following the pattern in Vector3Normalize.

functions use radians, making this awkward to use.

Allow to choose which modules are compiled with raylib, if some modules are excluded from compilation, required functionality is not available but smaller builds are possible.

* Expose GetRenderWidth and GetRenderHeight functions

* Fix scissor on macos

* Fix typo

if `BUILD_LIBTYPE_SHARED` is defined allow build as a shared dll
