|

* gdk/gdkrgb.c: fixed some bugs in the 565_d mode, and added a
|
||||
4bpp static_color mode (for vga displays). Also fixed a '64' value
|
||||
in the dither matrix, which was causing one pixel out of 16k to be
|
||||
dithered wrong.
|
||||
|
||||
* gtk/gtkpreview.{c,h}: Changed it to work with GdkRgb, gutting
|
||||
most of the contents. This is an API change - any apps that relied
|
||||
on the internal structure of GtkPreview will need some change -
|
||||
most notably in the use of reserved colors. The Gimp needed
|
||||
changes in this regard.
