Summary: wxStaticBitmap XPM transparency issue

Initial Comment:
If an XPM (such as the one attached) has more than one
colour defined as being "None", i.e. transparent, only
one of the colours (represented by the dot in this
case) actually comes out transparent.

I know it's odd to have more than one colour defined as
being transparent, but I didn't do it: KIconEdit
generated this file, after I saved as one thing and
then edited the icon to become the two cyan rectangles.
 Perhaps not surprisingly, wxGTK does not exhibit the
problem.

If it's the underlying rendering that's at fault and it
would be an unnecessary overhead to correct it, it
would be nice if a note could be added to the
documentation warning of the problem, as it represents
a difference in behaviour between platforms.

If the file breaks the XPM standard then it's
KIconEdit's fault!

Problem occurs in 2.6.3 and 2.7.0-1.
