2007-04-23Add comments about used blending equationPetri Hintukainen
Remove unused x_odd parameter from blend_???_exact functions
2007-04-18Alphablending optimizations:Petri Hintukainen
- validate palette alpha values in overlay manager (one check / overlay / palette index) instead of checking every alpha value twice for every blended pixel in every frame - remove unneeded calculations - approximiate expensive integer divisions with multiplication and shift
2007-04-10Rationalise __attribute__((packed)) usage.Diego 'Flameeyes' Pettenò
First of all, as we check the presence of the attribute in configure.ac and we generate the XINE_PACKED definition there, there's no need to do the work again on attributes.h. Also remove #pragma pack support for now, as the trick is just not neat enough, and as it is it's just noise. Make Wine, libdvdnav and nosefart use XINE_PACKED rather than doing their own checks, as they are less reliable.

modify blend algo to avoid division (too slow on some machines). Result is still acceptable. CVS patchset: 8093 CVS date: 2006/07/08 09:40:03
