Owen Taylor a2d1299475 Make gdk_colormap_sync private since it was never exported in a header
Fri Feb  2 17:16:09 2001  Owen Taylor  <otaylor@redhat.com>

	* gdk/x11/gdkcolor-x11.c (gdk_colormap_sync): Make
	gdk_colormap_sync private since it was never exported
	in a header file.

	* gdk/x11/gdkcolor-x11.c (gdk_colormap_new): Fill in
	colormap->colors[] for StaticGray, StaticColor colormaps.

	* gdk/gdkpixbuf-drawable.c: Fix problems where image->bpp
	was being used as if it was image->bits_per_pixel.

	* gdk/gdkimage.h, gdk/x11/gdkimage-x11.c: Save the bits-per-pixel
	for the image in the GdkImage structure since it isn't
	reconstructable, and we need it to handle packed types

	* gdk/win32/gdkimage-win32.c: Set image->bits_per_pixel. (I'm making
	the assumption that on Win32 image->bits_per_pixel == image->depth,
	always.

	* gdk/linux-fb/gdkimage-fb.c: Set image->bits_per_pixel.

	* gdk/gdkrgb.c (gdk_rgb_select_conv): Exit with an informative
	warning message if no converter can be found.

/* Types of images.
* Normal: Normal X image type. These are slow as they involve passing
* the entire image through the X connection each time a draw
* request is required. On Win32, a bitmap.
* Shared: Shared memory X image type. These are fast as the X server
* and the program actually use the same piece of memory. They
* should be used with care though as there is the possibility
* for both the X server and the program to be reading/writing
* the image simultaneously and producing undesired results.
* On Win32, also a bitmap.
