tdf#130768 speedup huge pixel graphics Cairo
For more information/documentation please refer to the bugzilla task Fixed a crash in CppunitTest_desktop_lib which led to a missing test of mpGraphics in OutputDevice::DrawTransformedBitmapEx. Other public methods test that and one of the goals of the cange was to use that method more often, so this may have never been detected before Change-Id: I10e57bd05db0c8cf868ff98d63f5af3d116a3015 Reviewed-on: https://gerrit.libreoffice.org/c/core/+/89230 Tested-by: Jenkins Reviewed-by: Armin Le Grand <Armin.Le.Grand@me.com>
