/*
|

|
Notes:
|
||||||
|
- input width and height need to be a multiple of block size
|
||||||
|
- LDR input is 32 bit/pixel (sRGB), HDR is 64 bit/pixel (half float)
|
||||||
|
- dst buffer must be allocated with enough space for the compressed texture:
|
||||||
|
4 bytes/block for BC1/ETC1, 8 bytes/block for BC3/BC6H/BC7/ASTC
|
||||||
|
the blocks are stored in raster scan order (natural CPU texture layout)
|
||||||
|
- you can use GetProfile_* functions to select various speed/quality tradeoffs.
|
||||||
|
- the RGB profiles are slightly faster as they ignore the alpha channel
