The function means to accept a const * so let's declare it.
Will allow passing const buffers in games.
Also constness is next to godliness!

Samples count was not properly calculated on WAV loading

Start removing old rRES functions.

log2() is not available in some standard C library implementations

Replaced LUA by Lua

texture.mipmaps value needs to be updated, so, texture must be passed by
reference instead of by value

Mask was wrongly applied to 8-bit font image, it generated dark borders
on the font. Grayscale image has to be considered as the alpha mask for
a completely white image to use it correctly.

Functions that need to manage big data arrays don't work properly, that
functionality should be reviewed...

Updated to raylib 1.6 functionality

Correcting details that pop-up when testing the different platforms

Working on an updated version...

Still not working correctly, font offsets are not considered
correctly...

Support by default unordered charsets

new function: GetGamepadAxisCount()
new function: IsGamepadName()

Still requires some testing...

LoadSpriteFontTTF() - TTF font loading with custom parameters

Added funtion: GetGamepadButtonPressed() - This function can be useful
for custom gamepad configuration
