libjpeg-turbo: updated to 2.1.4

2.1.4

Significant changes relative to 2.1.3

Fixed a regression introduced in 2.1.3 that caused build failures with Visual \ 
Studio 2010.

The tjDecompressHeader3() function in the TurboJPEG C API and the \ 
TJDecompressor.setSourceImage() method in the TurboJPEG Java API now accept \ 
"abbreviated table specification" (AKA "tables-only") \ 
datastreams, which can be used to prime the decompressor with quantization and \ 
Huffman tables that can be used when decompressing subsequent "abbreviated \ 
image" datastreams.

libjpeg-turbo now performs run-time detection of AltiVec instructions on OS \ 
X/PowerPC systems if AltiVec instructions are not enabled at compile time. This \ 
allows both AltiVec-equipped (PowerPC G4 and G5) and non-AltiVec-equipped \ 
(PowerPC G3) CPUs to be supported using the same build of libjpeg-turbo.

Fixed an error ("Bogus virtual array access") that occurred when \ 
attempting to decompress a progressive JPEG image with a height less than or \ 
equal to one iMCU (8 * the vertical sampling factor) using buffered-image mode \ 
with interblock smoothing enabled. This was a regression introduced by 2.1 \ 
beta1[6(b)].

Fixed two issues that prevented partial image decompression from working \ 
properly with buffered-image mode:

Attempting to call jpeg_crop_scanline() after jpeg_start_decompress() but before \ 
jpeg_start_output() resulted in an error ("Improper call to JPEG library in \ 
state 207".)
Attempting to use jpeg_skip_scanlines() resulted in an error ("Bogus \ 
virtual array access") under certain circumstances.
