Changeset 308 for trunk/src/gui/painting/qwindowsurface_raster.cpp

Timestamp:

Nov 10, 2009, 1:49:03 AM (16 years ago)

Author:

Dmitry A. Kuminov

Message:

gui: Use manual image flipping (from Qt to PM) instead of setting the world transformation matrix. Added a simple pixel/ms counter for measurements.
