We can optimize ARGB conversion using SIMD (SSE2 or SSSE3). At result of simple unit test, this code will be improved about 50% on Core 2 processor.

Makoto, has this conversion been a bottleneck for you?

No, this is just a idea patch. This code can optimize code by SIMD.

In libjpegturbo we can decode directly to RGBX I think we should do this before worrying about optimizing this transformation.

OK. about libjpeg-turbo, I will handle bug 584652. To use it, we need BGRA support on qcms and etc.
