* Correction of values used only once in GenMeshCubicmap
The mapWidth and mapHeight values were only used as a limit in the for loop when they could be used throughout the function.
* mapWidth and mapHeight removed from GenMeshCubicmap
mapWidth and mapHeight have been removed from GenMeshCubicmap in favor of using cubicmap.width and cubicmap.height
Checking `<= x + w` causes off-by-one error where `CheckCollisionPointRec` will return true at the same time for two rectangles rendered right next to each, but which don't overlap (e.g. when making a 2D tile editor). This is clearly not what was intended.
* Update raudio.c
Review `raudio.c`: rewritten `ExportWaveAsCode()` to be more like rtextures.c `ExportImageAsCode()'
* no tab november
accidentally inserted a tab somewhere. corrected it.
When `i` starts with `0`, `t` is also `0`, which results in `previous == startPos == current`, this segment is not only redundant, but it also causes division-by-zero since `sqrtf(dx*dx + dy*dy)` is zero.
* Fix GetCodepointNext to return default value with size=0 on invalid input. Modify LoadCodepoints to work when GetCodepointNext returns a size of 0. All internal use of GetCodepointNext and GetCodepointPrev checked. This fix may break external code dealing with invalid input as the old code erroneously never returned a size of 0, external code that doesn't properly check for size=0 may endlessly loop or overflow a buffer on invalid input.
* Change default behaviour of GetCodepointNext to return a size of 1 instead of 0. This matches existing prod behaviour and guarantees size 1..4 is returned. Simplify internal code that uses GetCodepointNext that previously had to account for size=0.
* Simplified progressing through a UTF-8 string in ImageTextEx and MeasureTextEx. This change matches existing precedent in DrawTextEx
* GetCodepointNext: Add 10xxxxxx checks to multibyte encodings.
