8f440223f6 swscale: disable full_chroma_int when converting to non-24/32bpp RGB. 
This functionality is only implemented for RGB24/32 and causes crashes
otherwise.

8a8d0ce208 swscale: for >8bit scaling, read in native bit-depth. 
For 9/10bit, it means we don't have to upscale to 16bit before
actual scaling or pixel format conversion, and thus a performance
gain.

ef1ee362b3 swscale: implement >8bit scaling support. 
This means that precision is retained when scaling between sample
formats with >8 bits per component (48bit RGB, 16bit grayscale,
9/10/16bit YUV).

13a099799e swscale: change prototypes of scaled YUV output functions. 
Remove unused variables "flags" and "dstFormat" in yuv2packed1,
merge source rows per plane for yuv2packed[12], and make every
source argument int16_t (some where invalidly set to uint16_t).
This prevents stack pollution and is part of the Great Evil Plan
to simplify swscale.

dc179ec819 swscale: split yuv2packedX_altivec in smaller functions. 
This will likely lead to a considerable performance boost,
since it removes a branch from the inner loop. Part of the
Great Evil Plan to simplify swscale.

a6213f3dce build: Remove redundant config.mak includes from subdirectory Makefiles. 
Calling Make from subdirectories is not supported and config.mak has
multiple inclusion guards anyway, so the top-level include is enough.

0793531859 Bump major version for b8e893399f 
On architectures such as x86 (both 32 bit and 64bit), the stack element
size is fixed, which maintains alignment.  Here, this change does not
break anything. However, we also support also other architectures where
this property is not maintained and therefore, applications will crash
horribly.

This change effectively forces all applications to be recompiled against
libswscale.

9f63211175 swscale: split out RGB48 output functions from yuv2packed[12X]_c(). 
This is part of the Great Evil Plan to simplify swscale. Note that
you'll see some code duplication between the output functions for
different RGB variants, and even between packed-YUV and RGB
variants. This is intentional because it improves readability.

6d4d483eee swscale: de-macro'ify RGB15/16/32 input functions. 
Inline functions are easier to read, maintain, modify and test,
which justifies the slightly increased source size. This patch
also adds support for non-native endianness RGB15/16 and fixes
isSupportedOutput() to no longer claim that we support writing
non-native RGB565/555/444.

a27db4c349 swscale: fix function declaration keywords in x86/swscale_template.c.

inline for functions that must be inlined for performance reasons.

9bcbb250e2 swscale: fix types of assembly arguments. 
This prevents the following compiler warnings: "warning:
initialization from incompatible pointer type". Since the
variables are only ever used in inline assembly, their type
is actually irrelevant (so the part where it was wrong did
not invoke any buggy behaviour).
