MOAIImage:fillRect() is incorrect when using (0, 0, 0, 0) color

[Vavius]

Can be reproduced with samples/image-fillRect/ - change fill color from yellow to blank (0, 0, 0, 0) and you'll see that wrong rect is being cleared. Something is wrong with ZLBitBuffer::Clear.

can still repro ( i think ) with 1.7 build here : http://moaiforge.com/samples/sample-browser/player/index.html#image-fillRect
