It is used to select functions that work with 9-15bits.

Make sure the scaling functions for the 9-15bits are used for
9-15bits bit depths correctly.

Follow a 420, 422, 444 order instead of a random one.
This simplifies double-checking additions of new formats.

Split version files into one line per symbol/directive to allow compatibility
with the Solaris linker without preprocessing and eliminate $ from version file
templates to simplify the postprocessing shell command.

These warnings conflict with system macros on Solaris, producing
truckloads of warnings about macro redefinition.

Restore alphabetical order in lists, break overly long lines, do some
prettyprinting, add some explanatory section comments, group parts
together that belong together logically.

Based on the original documentation found in mpeg2dec (1995).

Casting the left-most byte to unsigned avoids an undefined
result of the shift by 24 if bit 7 is set.

yuvPlanartouyvy_c and yuvPlanartoyuy2_c are affected.

sws_getCachedContext is not a full replacement for the function.

Based on a long debug session with Kostya.

The rationale is that you have a packed format in form
<greyscale sample> <alpha sample> <greyscale sample> <alpha sample>
and shortening greyscale to 'G' might make one thing about Greenscale instead.
An alias pixel format and color space name are provided for compatibility.

Blackfin is a painful platform to work with, no test machines are available
and the range of multimedia applications is dubious. Thus it only represents
a maintenance burden.

Instead of setting FFLIBS in each library Makefile configure
exports FFLIBS-$library in config.mak.

Prevent a division by zero down the codepath.
