7b72a84d87 Add a working directory for PVR lib tests 
Unfortunately, the WORKING_DIRECTORY directive for ADD_TEST seems to be broken as of CMake 2.8.10, fortunately there was a mail thread about this issue in 2.6 so I was able to implement the workaround.

6149c0af3a Add PVR tests 
If cmake was able to find Imagination's PVR library, then it'd be nice to make sure that our decompressor matches theirs. We incur a bit of overhead by adding .pvr files into git, but hopefully this cost will be beneficial to actually figuring out how things are working...

abd4ba8b54 Abstract away some utilities that we can use across all of our tests, and add a test for a gray image. The test currently seems to be failing, which is likely due to a bug in our bit depth manipulation code. 2013-09-04 20:20:37 -04:00

ab0dbbfa6e Bugfix 
The bug was that bitIdx was not being taken into account when we realized that there was enough pixel depth to stay within the current byte when reading pixel values.

53e7879742 Add PVRTC Pixel class 
This class accepts a pixels with up to 8-bit components. With the way PVRTC is laid out, there are many different bit modes that we could run into. This lets us change between any that we'd like to deal with.
