d37548299f Run the TurboJPEG conformance tests out of a directory in /tmp (for improved performance, if the source directory is on a remote file share.) Fix an issue in TJBench.java that prevented it from working properly if the source image resided in a directory with a dot in the name.

3d037a5c72 Refactored YUVImage Java class so that it supports both unified YUV image buffers as well as separate YUV image planes; modified the JNI functions accordingly and added new helper functions to the TurboJPEG C API (tjPlaneWidth(), tjPlaneHeight(), tjPlaneSizeYUV()) to facilitate those modifications; changed potentially confusing "component width" and "component height" terms to "plane width" and "plane height" and modified variable names in turbojpeg.c to reflect this; numerous other documentation tweaks

66f830135f Clean up and consolidate notes regarding the YUV image format. This also corrects a factual error regarding the padding of the luminance plane-- because we now support 4:1:1, the component width is not necessarily padded to the nearest multiple of 2 if horizontal subsampling is used.

0c0d0bc5b1 Fix the build of the Java classes when using MSVC 2010 and later. Something in the recesses of my brain is telling me that I tried this before and it failed under some circumstances, but it must have been a bug in an older CMake implementation. CMake 2.8.8 and later seem to work fine with this patch. This patch also updates the minimum required version to 2.8.8, because 2.8.8 fixed another issue that was preventing the SIMD code from building under MSVC 2010 and later.

2a10cbaa27 Fix an issue that prevented tjEncodeYUV2() and TJCompressor.encodeYUV() from working properly if the source image was very tiny. Basically, jpeg_start_compress() was attempting to write the JPEG headers, which was overrunning the YUV buffer. This patch removes the call to jpeg_start_compress() in tjEncodeYUV2() and replaces it with calls to the individual routines that are necessary to initialize the color converter and downsampler. TJUnitTest has also been modified to test for this condition (the buffer size regression test now works in YUV mode.)

7a0bc500e2 Deprecate and undocument the FORCE{MMX|SSE|SSE2|SSE3} flags. These were originally introduced in TurboJPEG/IPP as a way to override the automatic CPU selection in the underlying IPP codec, which was closed source.
