NAME
       gl_putboxmask - copy a masked  pixmap to a rectangular area

SYNOPSIS
       #include <vgagl.h>

       void gl_putboxmask(int x, int y, int w, int h, void *dp);

DESCRIPTION
       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.
