Just got back, and started reading your patches; this is some really
nice work :-) I love deleting huge gobs of mostly pointless code -
that's great fun.

It is entirely likely that the MaskColor will only be used if the icons
are not alpha-transparent bitmaps :-) it might be worth looking at what
the DEFAULT_IDLIST is to see if any are.
We may find that the "MaskColor" code is another total anachronism that
we can throw out, along with the other dinosaurs :-) no doubt there is
some place that it is used, but ...
If we could verify that it is only used for non-alpha Bitmaps - then
(perhaps) we could simply check all of default_images for non-alpha
bitmaps, and isolate any remaining places more easily.

Well - the res files are referred to by ID, so if you have:
I -think- that there needs to be an RID_DEFAULTIMAGELIST_SC reference
in the code somewhere; unless this is some special case for ensuring
that res/commandimagelist/* ends up inside the .zip file [ AFAIR we
subset only mentioned icons - which perhaps we could stop doing too ]

Shame; wastes time, and memory.

If icon theme change works correctly (and we should be updating on that
properly of course), then we don't need it. I suppose in the cases where
changing the contrast setting works it might be worth simply re-using
that code for theme change (if there is no equivalent code for that).

Right ! we should have a single set of style colors; and simply use the
right colors from the color theme for high-contrast mode rendering. That
is important because it also enables the mirror impairment that requires

Oh - great list; I'll try to put some time this week into prodding the
icon theme building code so we can start actually removing these from
the default_images directly, and move them into a separate high-contrast
theme one by one as we remove the need for them.
