|

|

* gdk/gdkrgb.c (gdk_rgb_select_conv): Improved the 24bpp
|
||||
conversion selection logic, so Suns and other big-endian
|
||||
machines should get faster conv routines. This is also the
|
||||
point where 4bpp gray and 1bpp are checked in, although I
|
||||
wouldn't be surprised if 1bpp is a little buggy. This is
|
||||
synchronized with the 0.0.7 release of GdkRgb.
|
||||
|
||||
* gtk/Makefile.am:
|
||||
* gtk/testrgb.c: Checked in testrgb.c to CVS, and made the
|
||||
appropriate change to the Makefile.am
