b18f8cbf3d Revert two swscale commits. 
Revert "swscale: update context offsets after removal of AlpMmxFilter."
(commit a95e3fa90b)
and
Revert "swscale: Remove some write-only variables related to alpha handling."
(commit 9d03cb9fc5).

They broke alpha handling - it's the evil inline asm that still uses that
variable, so it's not truely write-only.

25c42234a9 swscale: make monowhite/black RGB-independent. 
Disadvantage is that it no longer allows modifying brightness through

no longer need to be identified as a RGB format.

dae2ce361a swscale: enforce a minimum filtersize. 
At very small dimensions, this calculation could lead to zero-sized
filters, which leads to uninitialized output, zero-sized allocations,
loop overflows in SIMD that uses do{..}while(i++<filtersize); instead
of for(i=0;i<filtersize;i++){..} and several other similar failures.
Therefore, require a minimum filtersize of 1.

Fixes problems where rgbToRgbWrapper() is called even though it doesn't

Fourthly, fixes crashes when converting from e.g. monowhite to
monowhite, which calls planarCopyWrapper() and overwrites/reads because
n_bytes != n_pixels.
