8c40ac8ae6 Add TurboJPEG C example and clean up Java example 
Also rename example.c --> example.txt and add a disclaimer to that file
so people will stop trying to compile it.

739edeb8a6 Further exception cleanup 
Use a new checked exception type (TJException) when passing through
errors from the underlying C library. This gives the application a
choice of catching all exceptions or just those from TurboJPEG.

Throw IllegalArgumentException at the JNI level when arguments to the
JNI function are incorrect, and when one of the TurboJPEG "utility"
functions returns an error (because, per the C API specification, those
functions will only return an error if one of their arguments is out of
range.)

Remove "throws Exception" from the signature of any methods that no
longer pass through an error from the TurboJPEG C library.

40dd3146cd 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

fc26b6577a Extend the YUV decode functionality to the TurboJPEG Java API, and port the TJUnitTest modifications that treat YUV encoding/decoding as an intermediate step of the JPEG compression/decompression pipeline rather than a separate test case; Add the ability to encode YUV images from an arbitrary position in a large image buffer; Significantly refactor the handling of YUV images; numerous doc tweaks; other Java API cleanup and usability improvements

b14813947e Streamline the BufferedImage functionality in the compressor so that it works the same way as compressing a "normal" image, and deprecate the old BufferedImage methods and other redundant methods. Eliminate the use of deprecated features in the test programs.

b2f9415a63 Slight refactor to put ScalingFactor into its own class (mainly because the $ in the class name was wreaking havoc on the build scripts, but also to add a few convenience methods to it) and to create a separate loader class so we can provide a .jar file with the MinGW distribution that loads the correct DLL
