I'm programming in C with xlib (standart libs).
I need set GC with transparent pixmap (in some pixels).
I have colored pixmap, that set tile for GC via XSetTile. This pixmap is painted on all screen.
And I have mask, created by this pixmap. This mask is set by XSetClipMask.
But mask is set only for one pixmap, that stay in (0, 0).
How I can multiple this mask on all screen?
