if (${PLATFORM} MATCHES "Desktop")
  target_link_libraries(${RAYLIB}_shared glfw ${GLFW_LIBRARIES})

was never true because PLATFORM STREQUAL "PLATFORM_DESKTOP"...

This fixes #551 and makes the changes suggested in #552 (commited as 965cc8ab)
unnecessary.

Fixes: e1e036a6 ("Disable glfw only when it is not found and not external", #558)

This function was added in text module as GenImageFontAtlas()

Rotate a Vector3 by a Quaternion

Added: data to CharInfo struct
Added: LoadFontData()
Added: GenImageFontAtlas()
Removed: LoadFontEx()
Removed: LoadTTF() [internal]
Some code tweaks

- GetImageData()
- GetImageDataNormalized()

...by emscripten glfw javascript implementation

Reviewed: GetImageData()
Reviewed: ImageFormat()

ImageDraw() code tweak

Added note idea on ImageFormat() for future redesign (to support
16bit-32bit pixel-formats)

Not used in raylib this mechanism

Replaced by fabs() that seem to work ok

It seems TCC was not casting correctly int values to float in some
specific situations

Added android_native_app_glue module to raylib compilation instead of
compiling it as static lib at apk generation.

Did this ever work? Surely, doesn't look like it...

Not sure if this ever worked, but now it at least compiles.

Release, unless we are in a Git repo, then it's Debug.
