It's incredibly slow - ~60 seconds to compress a 512x512 image, on a Core i7 - but it works. - Added AVPCL compressor to projects and got it building with VC9 and VC10. - Removed unused command line interface & file read/write code from AVPCL. - Convert AVPCL to use NV vector math lib, asserts, etc. - Convert AVPCL to use double instead of float. - Added 4x4 symmetric eigensolver, for AVPCL; it's based on the existing 3x3 one, but I had to rewrite the Householder reduction stage. As with ZOH, using the eigensolver (instead of SVD) gives a ~25% speedup without significantly affecting RMSE. - Encapsulate ZOH and AVPCL stuff into their own namespaces to keep everything separate. - Added some missing vector operators to the nvmath lib.	11 years ago

Add BC7 support. It's incredibly slow - ~60 seconds to compress a 512x512 image, on a Core i7 - but it works.

- Added AVPCL compressor to projects and got it building with VC9 and VC10.
- Removed unused command line interface & file read/write code from AVPCL.
- Convert AVPCL to use NV vector math lib, asserts, etc.
- Convert AVPCL to use double instead of float.
- Added 4x4 symmetric eigensolver, for AVPCL; it's based on the existing 3x3 one, but I had to rewrite the Householder reduction stage.  As with ZOH, using the eigensolver (instead of SVD) gives a ~25% speedup without significantly affecting RMSE.
- Encapsulate ZOH and AVPCL stuff into their own namespaces to keep everything separate.
- Added some missing vector operators to the nvmath lib.
