Trying a new optimization approach, some additional functions added, they will be probably exposed soon.

Despite all the effort put on function optimization, dealing with alpha blending is complex, considering src and dst could have different pixel format...

Optimized to avoid ImageCrop() calls, now we define the source image rectangle and we just copy that data over the new canvas.

Always using RGBA for now.

Further optimization, moving data line-by-line
Old optimization left for reference

Using ImageResizeCanvas()

Now uses GetImageAlphaBorder()

Avoid GetImageData() retrieval and free

Added several optimized options for future reference (if required)

- 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()
