some do... so many brandings of it, its hard to tell really - and as most Operating system have builtin things to distinghuish between all of them blah blah.
personally i'd say fudge it and create me own dang format

... use a TGA to map out everything in my 3d package and then export 2 bitmaps, one 24bit colour the other a 256 greyscale alpha ... import both into db
export as my image type which is constructed into a 32bit memblock on loading
you have 4 byte positions per pixel
RED GREEN BLUE ALPHA ... 0 - 255 values
no problem importing your own format as long as you understand the codec you make for it (^_^)
