* gdesktop.h: Added extern declarations for the want_transparent_icons and want_transparent_text variables. * gtrans.c (set_window_text): Now we use the new global variables want_transparent_icons and want_transparent_text to decide how to paint the pixmap and mask. The want_transparent_* variables can thus be configured for the smartness/speed of your X server when using shaped windows.
