This patch still does not work on PPC.

For free PPC accounts (you will need to probably write C test files; but it will let you test)

Updated diffs and some extra testing code: testgif.tgz (DOES NOT contain a
subdirectory; untar directly within the intended destination)
Changes from the previous patch:
* Fixed the call to gdip_is_an_indexed_pixelformat that did not actually
call the function because it was missing the argument list.
* Added indexed loading & saving support to gifcodec.c.
* Updated Image.Palette to behave like Microsoft's implementation. I
discovered its bizarre behaviour when I tried to write a program for the
Microsoft framework to save an indexed 8-bit Bitmap with a custom palette.
It does not actually behave like a property, and should really have been
engineered as two separate functions, since there is no persistence
involved. Reading from the property creates a new instance of
System.Drawing.Imaging.ColorPalette and fills it from the underlying GDI+
GpImage object. However, the underlying GpImage's palette is only updated
if you assign to the property. Since you are not allowed to create
instances of ColorPalette directly, you end up having to write code like this:
ColorPalette palette = my_bitmap.Palette;
for (int i=0; i < palette.Entries.Length; i++) palette.Entries[i] = Color.FromArgb(ar, gu, ments);
my_bitmap.Palette = palette; /* assign the same instance back! if this is
skipped, the image file will display and save with the old palette */
This is not documented in MSDN! But whatever the case, mono now behaves the
same way.
Oh, and one other thing: This time I actually verified that the diffs apply
cleanly :-)
