e3357083d7 GRAPHICS: Change another interpolation function in Edge filter. 
A 2 to 1 interpolation was causing errors. It is fixed, renamed, and
moved to the common interpolation file.

3d57c13af0 GRAPHICS: Add dummy specializations for some interpolate* functions 
They use ColorMask values not present in 2-byte ColorMasks. Since they
should never be used on 2-byte pixel data, the dummy implementations
assert(0) and should be removed by any optimizing compiler since no
code path can ever reach them.

a5bc89102e ALL: Remove obsolete register keyword 
The register keyword was deprecated from the C++11 standard,
<http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4193.html#809>,
and removed from the C++17 standard,
<http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4340>, so
cannot exist in a well-formed C++17 program.

It has never done anything in GCC
<https://gcc.gnu.org/ml/gcc/2010-05/msg00113.html>
and because of the way it is specified in the standard, it is “as
meaningful as whitespace”
<http://www.drdobbs.com/keywords-that-arent-or-comments-by-anoth/184403859>.

The one remaining use of the register keyword is in the DS backend,
where it is used to create a local register variable using the
non-standard GCC Extended Asm feature.

Closes gh-1079.

This caused createThumbnail() to crash, e.g. when saving in the
Kyrandia engine. Probably other engines as well.

adf8cee449 GRAPHICS: Allow arbitrary input sizes for thumbnail scaling. 
Instead of a fixed 1/2 or 1/4 scaling we do a two step scaling now:
1) Scale image to width < 160*2 && height < [100,120]*2 with 1/4 or 1/2
   nearest-neighbor.
2) Use a bilinear scaler to scale aspect preserving to 160x[100,120]

This fixes bug #3614568 "GRAPHICS: Odd thumbnail sizes crash".

Scalers are actually fixed at 2Bpp right now and not at the
depth of OverlayColor.

a4798602d7 JANITORIAL: Fix missing whitespace in pointer cast 
find -name '*.h' -or -name '*.cpp' | xargs sed -r -i 's@\(([A-Za-z0-9]+)\*\)@(\1 *)@g'

This seems to have caught some params as well which is not undesirable IMO.
It also caught some strings containing this which is undesirable so I
excluded them manually. (engines/sci/engine/kernel_tables.h)
