1afb8e714b Fixing BASISU_DEVEL_MESSAGES for MSVC. 2019-05-10 22:33:52 -07:00

130eb9f115 Major compression performance/quality improvements, for a 15-35% or so decrease in file size for the same Y PSNR/SSIM. The basis file format has changed due to these optimizations.
Increasing the max codebook size to 16K vs. 8K, for a major increase in the max achievable quality.
Adding exception catching to command line tool.
Enabling debug iterators on MSVC.
Refining command line options, adding "-individual" flag to create multiple .basis files (vs. a texture array).
Changing default colorspace to sRGB, because that's probably the best default. -linear disables this and uses linear colorspace metrics.
PNG reader in 32-bit builds checks the size of the file before loading to avoid out of memory exceptions.

33996b1a5f Important: Changing the Basis file version, so any existing files will need to be recompressed!
Adding new fields to the basis header: texture type and framerate. Texture type may be 2D, 2D array, video, volume, or cubemap array. The compressor makes sure that anything other than pure 2D follows certain constraints (cubemap arrays must have a multiple of 6 input images, videos/texture array images all must have the same resolution/# of mipmaps, etc.)
When unpacking cubemaps, the -unpack command now writes cubemap .KTX files which various tools like PVRTexTool support.
