REM Create a series of compressed textures versions of the file name passed in. Skips files which already
REM exist, since script can be very long running.
REM arg 1: file
REM arg 2: file without extension
REM arg 3: Y when need alpha, else N
REM arg 4: Q when best image required, else D for developer quality

REM -i specifies the input file passed as the first arg (full path) dos use 1%
REM -pot + indicates force power of 2
REM -m indicates to generate mipmaps
REM -f is the format, variable type (UBN unsigned byte normalized), colorspace
REM -q indicates how much time to spend, varies by encoding type
REM -o specifies output file name, uses arg without extension adds -family.ktx
