Yes - that would be the CG API version of the LibGraphics API - I did 
say it was similar :)

I wasn't suggesting that ssmple code example was an example of features 
LibGraphics has which CoreGraphics does not (although I can see how it 
could be read like that - oops).

LibGraphics incorporates various features relating to bitmap effects in 
its API. CoreGraphics only has 'drop-shadow' abilities - LibGraphics 
does the whole stack of bitmap effects you see exposed via the 
bitmapEffects property. It also has a number of gradient types which 
CoreGraphics does not support.

Eventually LibGraphics will (hopefully) have APIs added to enable the 
range of filter processing operations SVG allows - in order to expand 
SVG support in the future (again, something CoreGraphics does not have).

Warmest Regards,

Mark.
