I'm not sure what's going on, but perhaps the issue is with the Ico[n] loader.

You're saying that if you use PNG then it works.  But on Windows, you need
ICO files otherwise File Explorer won't show them.

The embedded icons [the ones the Resource Compiler inserts into your .EXE files]
of course also needs ICO files.

Perhaps ICO files aren't deserialized properly from their reswrapped representation.

Try to see if this is the case by sticking that same icon [foxburnerIconSmall
or foxburnerIconBig] onto an FXButton and check if it shows up in the GUI.

If it doesn't show up then there's the issue.

I'm thinking maybe there is an ICO format version that FXICOIcon and FXICOImage
loaders don't understand.  On Windows, the icon shown on the taskbar is snarfed
from the ICON section in your .exe, so the reswrapped and deserialized version
of the icon are not used.  Maybe thats why it shows up there.

On Linux, the icon must be deserialized from its reswrapped, compiled-in data-
array and if its a format we don't understand then the image will be blank.
