Give OS_GBPB a larger buffer to enumerate the themes, and post filter those that are too long for the gadget (rather than bailing out with a buffer overflow error).
Correct a discrepancy between the gadget buffer size and #define.
Correct the fallback button well colour (when not given explicitly) to not be light blue, due to WimpVisualFlags wanting RGB values rather than palette entries.
