* Early exit from QRegion::intersects() if there is only one rect.Andreas Aardal Hanssen2009-06-161-0/+2
| | | | | | | | | | Don't waste cycles with constructing a vector with rectangles if there is only one rectangle in the source region. Same as 36ff1b507bf2d509019ae8ddd638922b09755c6b, but for QRegion::intersects(QRect). Reviewed-by: bnilsen
* Early exit from QRegion::intersects() if there is only one rect.Andreas Aardal Hanssen2009-06-161-0/+2

* implement equality operator in a more sane wayLars Knoll2009-06-154-5/+56
| | | | | | | | | | | | Using qFuzzyCompare for checking whether two transformations are equal doesn't give us too much and is inconsistent with our other matrix classes. Using simple floating point equality is a lot faster as well. Added qFuzzyCompare overloads for QMatrix and QTransform to still allow for fuzzy comparisons. Reviewed-By: Samuel Rødal

* Fixed bitmap drawing in GL 2 engine when not using GL pixmap backend.Samuel Rødal2009-06-121-1/+3
| | | | | | | | | QPixmap shouldn't return true in hasAlphaChannel() for bitmaps, instead the paint engine should check whether the pixmap is a bitmap or not. In addition, QBrush::isOpaque() returned true for bitmap brushes, which is wrong according to the documentation. Reviewed-by: Trond

* | QPainter::worldTransform() does not return identity matrix.Bjørn Erik Nilsen2009-06-103-31/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QPainter::worldTransform() does not return identity matrix when created on a redirected widget. It should always be identity by default, and should only change as a result of QPainter::setWorldTransform. The reason it didn't return identity for redirected widgets, was that we translated the shared painter's world matrix directly. Since we cannot modify the world matrix directly, we have to store the shared painter's current world transform in a separate matrix (redirectedMatrix), reset the world transform to identity, and later combine the redirectedMatrix with world transforms set on the painter. Note that redirection_offset was in negative coordinates before, and that redirectionMatrix now is in positive coordinates, hence opposite signs around. Auto-test included.

| | | | | | | | | | | | | | | | | | | | | The artifacts were visible in the mainwindow demo when dragging the top toolbar separator left and right. We need to check that rect clipping is actually activated before we compare the new clip rect with the old, otherwise the clip type and clip bound flags won't get updated.

Using different depth values for the various clip parts also makes restore() very cheap when only IntersectClip is used. As an additional bonus this patch gives antialiased clip in the GL 2 paint engine. Task-number: 254658 Reviewed-by: Trond

Move the equality operator code back in (qFuzzyCompare) to avoid breaking many autotests. The change should go back in later on, possibly supplemented by a qFuzzyCompare(QTransform) function.
