[B2-devel] Native QuickDraw acceleration

[Gwenole B. <gb...@di...>]

Hi,

I have just committed a few arrangements for Native QuickDraw (NQD) 
acceleration hooks under Linux/PPC. With extra changes, it will be easy 
to clean the code for little-endian and 64-bit platforms. So far, 
performance improved by approx. 2x in emulated mode with MacBench 5.0 
CopyBits/srcCopy benchmark.

BTW, the following test should always yield true so I intend to remove 
it:
((uint32 *)p)[0x15c >> 2] > 0

I don't know about other magic values either. I think we should also 
benefit from a CopyBits() acceleration but I'd want to get some NQD 
stuff done first.

Bye,
Gwenole.
