// --------------------

//
|
|
// we are always working with a 32 bit deep pixel buffer
|
|
// under QuickDraw its alpha parts are going to be ignored in the GWorld,
|
|
// therefore we have a separate GWorld there for blitting the mask in
|
|
|
|
// under Quartz then content is transformed into a CGImageRef representing the same data
|
|
// which can be transferred to the GPU by the OS for fast rendering
