Made small optimizations to Texture's SetRegion, SetLinearRegion, GetRegion and Clear. They might not be super effective depending on how the compiler already optimized them. The optimizations mainly focus on removing the multiplication when transforming a position to an index by using the row index rather than the y coordinate during iteration. Also fixed regions not drawing properly when clipping against the sides of a window and made GetRegion reject any region that isn't fully inside of the window (previously accepted regions that clipped outside of the right and bottom side, possibly leading to incorrect reads on the user end due to desynchronized region dimensions)
