- The Mouse struct already stores cursorOnScreen. This function simply exposes it to the usage code.

It could be useful in a future...

Switched custom WAV laoding/saving funtionality to drwav library, it also provides the required mechanisms to stream wav data.

Compression API requires functions provided by stbi_image_write (DEFLATE compression)

This change could introduce an issue on dataSize precalculation...

All functions requiring sizeof() now follow the same convention:

NUM_ELEMENTS*NUM_SUBELEMENTS*sizeof()

Several functions used to load external files have been reviewed to just load the full file with LoadFileData() and load data from memory from there. This way all file access functionality is centralized in utils module.

Functions reviewed: LoadDDS(), LoadPKM(), LoadKTX(), LoadPVR(), LoadASTC(), SaveKTX()

* added BLEND_SET

* renamed BLEND_SET to BLEND_ADD_COLORS

* Adding Norm and Remap functions

// Normalize input value within input range
// Remap input value within input range to output range

* Rename Norm to Normalize

To make it uniforms with Raylib's functions

* Calculate Remap without other functions

* Introduced Vector2 and Vector3 Square Lenght.

* Square length functions renamed

Current looping system was broken, `loopCount` has been converted to `bool looping` and user can enable/disable with `music.looping = false`. `SetMusicLoopCount()` has been removed.
