* Fix alpha blending regression with WA_StacksOnTop QOpenGLWidgetsLaszlo Agocs2019-03-301-0/+5
| | | | | | | | | | | | | | | | | 0bc42886898 in Qt 5.6 introduced support for premultiplied alpha in the raster-rendered QWidget content. Unfortunately this introduced a regression for OpenGL content from QOpenGLWidgets with WA_StacksOnTop set: these used standard alpha blending in 5.5 and earlier, and switching them to premultiplied (in case the - unrelated - raster content has a _Premultiplied QImage format) breaks all content that was done with non-premultiplied alpha in mind, for example the qopenglwidget example's "Transparent background" checkbox. Restore the pre-5.6 behavior. Fixes: QTBUG-74285 Change-Id: I76fcadd53cd436efa2b619b8d6739270995d044f Reviewed-by: Allan Sandfeld Jensen <allan.jensen@qt.io>

* Fix QColor::toCmyk() for rgb(0, 0, 0)Eirik Aavitsland2019-02-051-17/+22
| | | | | | | | | | | | | | We translate all pure gray colors into cmyk having c,m,y=0 and only the k value expressing the darkness. But a fix introduced to avoid division by 0 caused rgb(0, 0, 0) to be an exception to this; it ended up being translated as c,m,y,k=1 instead. Fix by catching the potential div-by-0 situation earlier and directly set the orthodox cmyk translation: c,m,y=0,k=1.

* Painter path stroking: fix capping of beziers ending in tight turnsEirik Aavitsland2019-02-051-13/+14
| | | | | | | | | | | | | For some overly tight beziers where the start or end point and the next control point are closer than the pen width, the stroker's shifting algorithm will produce a start/end tangent pointing in the opposite direction from what is expected, for one of the sides. This would break the square and round capping logic. Fix by detecting the situation in the capping function and reversing the tangent when necessary.

By default, generated files are compliant to v1.4 spec. v1.6 compliance must be enabled by, e.g., calling QPrinter::setPdfVersion() with QPrinter::PdfVersion_1_6.
