debian/patches/020130903-5ae4180-ps-interpreter-dont-interpolate-imagemask-data-for-high-level-devices.patch:
PS Interpreter: Do not interpolate imagemask data for high level devices.
This accelerates processing files with embedded bitmap images when the
output device is a high-level (vector) device. In this case an explicit
"-dNOINTERPOLATE" on the command line is not needed any more.
