Merge branch '4.6' of scm.dev.nokia.troll.no:qt/oslo-staging-2 into 4.6-integration
* '4.6' of scm.dev.nokia.troll.no:qt/oslo-staging-2:
revert f36fb8b2b63b3734cc2bd66b329ca4fef1204845
Read QWS_SIZE from layer rather than screen
Get rid of no_cast_from_ascii warning
Docs: Amendments to latest changes to QImageReader docs.
images: Document QImageReader::loopCount behaviour for infinite loops
gif: Add unit test for QImageReader::size calls
gif: 10% speedup on microbenchmark on QImageReader
png: Avoid calling QImage::scanLine(int) from within a loop
QImageReader: Avoid errorString creation in the normal case
Fix text rendering on GL2 paint engine
