* n64texconv and bin2c * mv tools/n64texconv tools/assets/ * fix * more light fixes * Silence -Wshadow for libimagequant * Add reference counting gc for palette objects in python bindings * Fix missing alignment in n64texconv_*_to_c functions Co-authored-by: Dragorn421 <Dragorn421@users.noreply.github.com> * Check palette size in n64texconv_image_from_png * accept memoryview as well as bytes for binary data * minimal doc on n64texconv_quantize_shared * fix a buffer size passed to libimagequant * assert pal count <= 256 on png write * Disable palette size check for input pngs, ZAPD fails the check * No OpenMP for clang * When reading an indexed png into a CI format, requantize if there are too many colors for the target texel size --------- Co-authored-by: Dragorn421 <Dragorn421@users.noreply.github.com>
