Fri Jan 30 08:51:16 1998 Federico Mena <federico@bananoid.nuclecu.unam.mx> * gdk/gdkcc.c (gdk_color_context_get_pixel): red/green/blue parameters are now expected to be in [0, 65535], to be consistent with the rest of Gdk. (gdk_color_context_get_pixels): Made it use 16-bit color values as well. Fixed mdist=1000000 buglet (it should start with at least 0x1000000). (gdk_color_context_get_pixels_incremental): Same as gdk_color_context_get_pixels().
