Please write in English, because the XEmacs maintainers do not have
translators to read other languages for them.
Please describe as succinctly as possible:

================================================================
Dear Bug Team!
I have the following code in my init.el file:
;; -------
;; Pointer used during garbage collection.
;; .xbm not supported under windoze
(if (and (file-exists-p "~/.xemacs/recycle-image.xbm")
(file-exists-p "~/.xemacs/recycle-mask.xbm")
(not running-windoze))
(set-glyph-image gc-pointer-glyph
(vector 'xbm
:file "~/.xemacs/recycle-image.xbm"
:mask-file "~/.xemacs/recycle-mask.xbm"
:foreground "black"
:background "chartreuse1"))
(set-glyph-image gc-pointer-glyph "recycle2.xpm"))
This worked great for, well years. However, I noticed recently that I
no longer get the recycle icon, I get a text message instead. If I use
the "recycle2.xpm" icon instead, I get an icon but it is black, not
green.
I tried it with -vanilla, but no change.
Has anything changed in xbm/xpm support?
Cheers,
Sean MacLennan

You've looked at the image files and they're ok? It's possible I
managed to bork them making a distro ... I'll look later.

The .xbm files are my own. The .xpm file looks fine. It even comes out
right if I open it as a .xpm file in XEmacs.

I recently saw something similar under windows. The glyph was somehow
wrong - but to me it was with black lines randomly over it ... was
related to a new graphics card... I know this is linux you're running,
but it couldn't pssibly be something like that?
bye. Adam.

This worked great for, well years. However, I noticed recently that I
no longer get the recycle icon, I get a text message instead. If I use
the "recycle2.xpm" icon instead, I get an icon but it is black, not
green.
I'm seeing this as well, but haven't tracked it down as of yet.
My top contender for why it's screwed up:
1) If you're using a 16-bit visual, you could be running out of colormap
entries or similar - at least on my box, the default visual looks like this:
default visual id: 0x23
visual:
visual id: 0x23
class: TrueColor
depth: 16 planes
available colormap entries: 64 per subfield
red, green, blue masks: 0xf800, 0x7e0, 0x1f
significant bits in color specification: 8 bits
Note that the green mask is 6 bits, but only 5 bits are available in
the colormap subfield - so it's possible to run out (I think). Depending
on window manager, and background images, your colormap may be running out.
I never really understood the semantics of how XAllocColor() is supposed to
work on a TrueColor visual in conjunction with colormaps, so....
I started seeing it (well, noticing anyhow) when I changed my was-showing-green X server
from a
1280x1024x24 config to a shows-black 1600x1200x16 config to support a bigger
monitor (the Intel i810 has a lame dot-clock with insufficient bandwidth to
do deeper than 16 bit at the higher resolution - the loss of color depth was
OK in exchange for 609,280 more pixels. ;)

I'm pretty sure that XAllocColor() just returns the closest colour on
"fixed" visuals (StaticGray, StaticColor, TrueColor). It only actually
"allocates" anything on visuals which have some form of programmable
look-up table (GrayScale, PseudoColor, DirectColor).
DirectColor is the case where I never managed to understand the
semantics of XAllocColor(). I'm not sure that anyone else does either;
every piece of code which I could find simply created a private
colourmap and initialised it to a ramp using XStoreColor().

Correct. The cells are allocated read-only, can be shared by multiple
clients. The actual color spec used and returned is the closest one supported
by the hardware.
DirectColor is the case where I never managed to understand the
semantics of XAllocColor(). I'm not sure that anyone else does either;
Here's my understanding: in DirectColor, you think in terms of color
planes rather that in terms of color cells. For instance, under a DirectColor
24 visual (8/8/8), due to the way pixels index the color cells, you can have
only 256 tints of each primary per colormap, and these tints are the same for
all colors in your colormap. Note that your hardware might know more than 256
tints in each primary, but can only handle that ammount at the same time[1].
Given this, XAllocColor works by looking at each primary in turn: if
you've already allocated enough different colors so that you've exhausted the
red planes, all X can do is use an existing value. Otherwise, it can allocate
a new one. In all cases, that builds the corresponding bitfields in the pixel
value, and this not only affects the color you're allocating (as in
PseudoColor visuals) but also *all* subsequently allocated colors that share
the same value for the red mask part. You then repeat the process for the
other components.
Footnotes:
[1] that's also why many displays support several TrueColor visuals of the
same depth: they implement different gamma curves of stuff like that.
