Helper indicating whether current pixel format is compressed or not.

This function is used in read_frame to check for corrupted frames.

Returns: true if pixel format is considered compressed by the driver, else false.

Warning: If kernel headers 3.17 or later are available, this function will rely on field 'flags', else will compare the current pixel format against an arbitrary list of known format codes.
