Rightclicking on brush selection button with preset active is surprisingly useless

[GoogleCodeExporter]

Supposing you have a preset type brush selected -- like a 3x3 diamond, say. If 
you rightclick on the brush selector, it makes the brush into something useless 
(the resultant brush has no solid areas, and therefore no effect).

IMO the correct behaviour would be to convert the brush to a normal 'grabbed' 
type brush with (current BGcolor) as the background, and the first non-BGcolor 
slot in the palette as the 'solid' parts of the brush.
(and then, of course, set the brush rendering mode to monochrome)

In the scenario that you describe, you may not have noticed, but grafx2 
restores the last color brush that you had picked (as if you had right-clicked 
the brush-grab button) AND makes it temporarily monochrome (BG color = 
transparent, all others = FG color). It's a non-destructive change, it reverts 
back to color brush if you right-click the brush-grab button again.

If you obtain a completely blank brush, it must be because the last brush you 
had grabbed was pure transparency (only BG color).
