- .basis transcoder class now validates the basis_slice_desc structs to ensure the original (unpadded) dimensions are valid, not too large (beyond 16K on either dimension), and are in sync with the slice's block dimensions. All methods that parse the slice desc structs now validate the contents first.
...
- basisu_lowlevel_etc1s_transcoder::transcode_slice(): Added PVRTC temp buf malloc buffer size sanity checking

tinyexr: upgrading to latest library version. We no longer modify tinyexr, i.e. the tinyexr.h header we're using is now completely standard. We direct tinyexr's zlib calls to our fork of miniz internally.

Changing C compression API for XUAST LDR: if unified quality level is not being used, and the lower level uastc_rdo_or_dct_quality parameter was set to 100, we would previously return an error. Now DCT is not enabled, as expected.

v2.1 update for KTX-Software and Khronos file format KTX2 compatibility.
...
This update impacts the UASTC HDR 4x4, UASTC HDR 6x6i, and XUASTC LDR formats. New KTX2 files in these specific formats using v2.1 can't be loaded using v2.0, however we've kept backwards compatibility with all of our previously written KTX2 files. (v2.1 can transcode all previously written files.)
This is part of our effort to be compatible with Khronos's specification.
bc6hf encoder's smooth block path updated to handle inputs with texels close to MAX_HALF_FLOAT.
Adding command line options to basisu tool so it can write either v2.0 or v1.6 compatible UASTC HDR 6x6i files. The default is v1.6.
Updating WebGL KTX2 testbed so on ASTC devices it automatically switches between sRGB or linear internal formats for the created texture.
