Copy a masked pixmap to a rectangular area
Usage
void gl_putboxmask(int
x,
int
y,
int
w,
int
h,
void
*dp);
Overview
Copy the contents of a memory buffer dp to a rectangular bitmap at position (x, y) with size (w, h).
This function works like gl_putbox, but does not write pixmap pixels of color zero. If the same pixmap is used often you should consider using the faster gl_putboxmaskcompiled(3).
Pixmaps are in row-major order. The source pixmap memory has the size w * h * BYTESPERPIXEL.
