Render bitmap with alpha channel.

Parameters
rSourceBitmapSource bitmap to blit
rAlphaBitmapAlpha channel to use for blitting
Returns
true, if the operation succeeded, and false otherwise. In this case, clients should try to emulate alpha compositing themselves

Render solid rectangle with given transparency.

Parameters
nXTop left coordinate of rectangle
nYBottom right coordinate of rectangle
nWidthWidth of rectangle
nHeightHeight of rectangle
nTransparencyTransparency value (0-255) to use. 0 blits and opaque, 255 a fully transparent rectangle
Returns
true if successfully drawn, false if not able to draw rectangle
