The ICM_DECOMPRESS_END message is sent to a video decompression driver to have it clean up after decompressing.
Returns ICERR_OK if successful. Otherwise, returns an error number.
The driver should free any resources allocated for ICM_DECOMPRESS_BEGIN.
ICM_DECOMPRESS_BEGIN and ICM_DECOMPRESS_END do not nest. If your driver receives ICM_DECOMPRESS_BEGIN before decompression is stopped with ICM_DECOMPRESS_END, it should restart decompression with new parameters.
