Matthew Hoops 4b05031042 Revert "VIDEO: Rework SVQ1 codebooks so they're endian-safe" 
This reverts commit 1ca81ee6ec.

I was wrong about them not being endian-safe before. Don't stone me.

Matthew Hoops e16ad39e53 VIDEO: Cleanup QTRLE 
In particular, the colors are not converted to the screen format upon decoding. The code should also now work with 32bpp screen formats.

Matthew Hoops 473a09786d GRAPHICS: Make YUV410 conversion code use bilinear interpolation

D G Turner 7b6c4bb8e1 VIDEO: Minor update to SVQ1 decoder, reversing sense of return flags. 
This changes the decoder function return flag meaning from "result
error" to "resultValid". This makes it more consistent with normal
C standard of returning 0 on success.

Matthew Hoops 8bf8a08048 VIDEO: Fix SVQ1 plane pitch

D G Turner 95d7c012d6 VIDEO: Minor updates to SVQ1 decoder, mainly return flags to bool. 
Since the returned int values from the decoding functions are just
0 for good or -1 for error, have changed these into an errorFlag
bool. This improves readability and cleans up some of the error
checking code. In addition, have fixed some oversights in formatting
spacing for readability.

D G Turner c917db0754 VIDEO: Change SVQ1 decoder to skip rather than decode embedded string. 
This string field is not used and this avoids having to include a
xor table.

This is a temporary workaround during development.
Keyframe (I) decoding is now working correctly, but Deltaframe (P) is

Max Horn 88913c0139 ALL: Remove trailing whitespaces 
This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
  git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'

Johannes Schickel 5e279996eb VIDEO: Prefer Surface::create taking a PixelFormat over the one taking a byte depth. 
Certain codecs seem to use a Surface with Bpp 2, but do not have any proper
format description. Whoever is maintaining these should check this commit and
fix the format properly.
