When I use the Glyph property, how do I know which color is transparent?

Delphi always assumes that the color of the bottom left-hand corner pixel is the background color and should be displayed as transparent. Yes, it took me a while to figure this out. It's not documented anywhere, but if you have the VCL source, you can look at the code in BUTTONS.PAS.
