OpenJPEG: improper use of opj_set_decode_area() for overviews

Description

Currently we wrongly use the opj_set_decode_area() API for overviews by using overview based coordinates, whereas openjpeg API is meant to be for full resolution. This happens to work by chance with openjpeg 2.2 or before a bit by chance, but this won't work with newer versions that implement subtile decoding and really expect coordinates passed to opj_set_decode_area() to be at full resolution
