Compress texture into DXT format.
true
for highQuality
parameter will dither the source texture during compression,
which helps to reduce compression artifacts but is slightly slower.If the graphics card does not support compression or the texture is already in compressed format,
then Compress will do nothing.In the Editor scripts, you probably want to use EditorUtility.CompressTexture, which will
compress using slower, but higher quality DXT compression.See Also: SetPixels function, EditorUtility.CompressTexture.
