TBitmappedButton is a simple custom drawn button which bases it's drawing
on provided raster images. Currently the following states are supported:
normal, down and focused.
The Caption of this button may have multiple lines of text, separated by any
line separator. The text is drawn centralized in the button.
Some work was done trying to achieve alpha blending for the button, but this
wasn't successfull. It would work like this: The button may be drawn flat
or alpha blended using a separate image for the Alpha channel. While pixels
in the alpha channel will result in the button pixel being fully drawn,
while black pixels represent pixels which aren't drawn. grey pixels are
alpha blended.
