Pavel Krajcevski a80944901e Refactor CompressionJob struct. 
In order to better facilitate the change from block stream order to non-block stream order,
a lot of changes were introduced to the way that we feed texture data to the compressors. This
data is embodied in the CompressionJob struct. We have made it so that the compression job
points to both the in and out pointers for our compressed and uncompressed data. Furthermore,
we have made sure that the struct also contains the format that its compressing for, so that if
any threading programs would like to chop up a compression job into smaller chunks based on the
format, it doesn't need to know the format explicitly, it just needs to know certain properties
about the format.

Moreover, the user can now define the start and end pixels from which we would like to compress
to. We can compress subsets of data by changing the in and out pointers and the width and height
values. The compressors will read data linearly until they reach the out pixels based on the width
of the given pixel.

Pavel Krajcevski 63a235958d When creating a compressed image from data make sure to set the block stream order based upon the format that you're compressing to. Yet more of this bug.... 2013-09-29 14:32:59 -04:00
Pavel Krajcevski 89fbaf8170 Keep track of the image size with the base image rather than the compressed image. It's not always the case that the image data is RGBA8 data. 2013-09-28 22:40:48 -04:00

Pavel Krajcevski 264e447e80 Deal with this bug once and for all. If we have an image in block stream order, then explicitly reorder it before doing any work. Then keep it that way. I probably could have fixed this in the amount of time I've wasted on it. -____- 2013-09-26 20:17:07 -04:00

Pavel Krajcevski 435f935de3 Update atomics compression algorithm 
In general, we want to use this algorithm only with self-contained compression
lists. As such, we've added all of the proper synchronization primitives in
the list object itself. That way, different threads that are working on the
same list will be able to communicate. Ideally, this should eliminate the
number of user-space context switches that happen. Whether or not this is
faster than the other synchronization algorithms that we've tried remains
to be seen...
