36 | // Implementation Notes | |
37 | // -------------------- | |
38 | // | |
39 | // we are always working with a 32 bit deep pixel buffer | |
40 | // under QuickDraw its alpha parts are going to be ignored in the GWorld, | |
41 | // therefore we have a separate GWorld there for blitting the mask in | |
42 | ||
43 | // under Quartz then content is transformed into a CGImageRef representing the same data | |
44 | // which can be transferred to the GPU by the OS for fast rendering | |
