472ecea71e Some of the IJG headers say "Modified by", so clarify that our "Modifications" are not referring to these.

a49c4e5247 The SIMD quantization algorithm does not produce correct results with the fast forward integer DCT and JPEG qualities >= 98, so for now, use the non-SIMD quantization function under those circumstances.

fc5dc4fa19 Some systems (notably OS X Leopard) have fls() already, so rename ours to avoid conflict

dc5db14a33 Move variable init around a bit to please crappy compilers.

35c4719638 Make sure the work space memory is properly aligned 
We use the heap allocators to avoid having more than one implementation
of the alignment logic.

dedc42e268 "Optimise" quantization step by replacing the division by a multiplication. 
This has no measurable difference right now but makes it possible to do
SIMD implementations of this stage.

59a3938b2e Framework for supporting SIMD acceleration 
Designed to impose minimal changes on the "normal" code.

49dcbfbf13 Split up the forward DCT routine into three stages 
Divide it into sample conversion, DCT and quantization in order to
easily provide alternative implementations of each stage.
