153b32391f New code for interpolate32_1_1 overflowed in 565 mode, so reverting to the old code (with some variable name changes to match the other interpolators)

4098ff66aa Removed use of LUT16to32 in HQx asm versions, replacing some MMX code with 'plain' x86 code. Advantage: got rid of a 256kb table (reduces cache load, so over here the code is about as fast as before; in particular, since the affected interpolators are not used that often, it seems). Moreover, the new code is more accurate than the old ASM code, which actually differed from what our C++ HQx did (sacrificing precision for speed, i.e., cheating ;-)

b93db9f30f HQX: Removed some more branches (like in my previous commit) from interpolation macros (they are meant to speed up things, but in reality cause a slowdown -- branches are expensive on modern CPUs)

16e7a7cd30 Turned two vars of the HQ2x/HQ3x ASM implementation into global vars, to make it possible to adjust them for 555 vs. 565 mode (555 mode is still a bit buggy, due to the interpolation code they use)

b51f2f3212 Implemented the OSystem framebuffer API, as discussed on scummvm-devel. All changes are just fine, and won't cause any compile problems or regressions, despite the fact that I can't test most of the non-SDL backend changes, at an improbability level of two to the power of two hundred and seventy-six thousand to one against - possibly much higher. Anything you still can't cope with is therefore your own problem. Please relax.

ea85e8c986 Moved ColorMasks to their own new header graphics/colormasks.h, so that both the scalers and the GUI code can access them. Also added (untested) entries for 1555, 444, 888 and 8888 modes

de250812e5 Removed my Altivec version of the hqx blitters, since it (a) didn't work with newer GCC versions, (b) speed was improved on some systems, but actually slower on others, and (c) even on my old 400 Mhz G4 hqx is fast enough w/o it

58eed3830b * 'make bundle' now copies the default theme files into the bundle. 
* Common::File will now look inside the application bundle on MacOS X for a file if
it can't find it anywhere else (so it'll find default-theme.ini and .zip)
* Cleaned up some #ifs.

c3d8674a26 Adds support for building on Intel Macs, using a modified 
version of patch 1448395 by Aubin and some of my 
own changes.

Notably:
* Two elements of a struct in backends/midi/quicktime.cpp
needed to be forced to BE.
* NASM set to build Mach-O binaries
* configure now checks for Altivec support on Darwin hosts,
instead of assuming it. Altivec support can also be disabled (not 100% sure if t
his is actually needed, but might be handy for crosscompiling).
* The aliasing of the symbols contained in the .asm files
done on Windows were also needed on MacOS.

Note that while the asm code is properly compiled and linked
in, HQ2/3x support will still not work properly on Intel macs
if NASM is enabled.
