* Remove warning from QColor::setNamedColor().Samuel Rødal2011-05-191-2/+1
| | | | | | | | | | | This warning is pointless as the user can anyway check if the color is valid after making the call by calling isValid(). Using isValidColor() could be used but it has a big performance overhead as validation then needs to be done twice.

* Fall back to using paths for large fonts in drawStaticText()Eskil Abrahamsen Blomfeldt2011-05-183-3/+46
| | | | | | | | | | | | | | QStaticText had an implicit risk which meant you had to make sure the text size did not grow unreasonably large. This was intended to avoid hiding the performance impact of using QStaticText for such a purpose, but it's too inconvenient. Thus, the same fall back as in drawTextItem() has been introduced. This will also fix a bug recently introduced when we started using the FT cache to draw static text in the raster engine, since this will fail for large fonts.

* New algorithm for drawing thin linesLars Knoll2011-05-126-1449/+1137
| | | | | | | | | | | | | | | | | | Added a new QCosmeticStroker class for drawing thin lines. The class can handle both aliased and antialiased lines. The code replaces all the midpoint line drawing algorithms in the raster paintengine and gives correct subpixel positioning for lines. It gives around 30% to 50% speedup against the midpoint algorithm. If we missed that fast path, the speedup is around between a factor of 6 to 8 for lines and aliased paths and 100 and 400 for antialiased paths.

* Fix QPainter::drawGlyphs() with non-affine transformationEskil Abrahamsen Blomfeldt2011-05-061-1/+8
| | | | | | | | | | | | | When the matrix has an non-affine transformation, the text will have to be rendered using the default path-renderer. This means going through the drawTextItem() path (since drawStaticText() has no support for those transformations) and it also means not pre-transforming the coordinates, since the default implementation of drawTextItem() supports transformations.

* Support gamma correction of text on GLEskil Abrahamsen Blomfeldt2011-05-031-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | If the SRGB framebuffer extension in GL is available, we can support gamma correction of text with a gamma of 2.1. On Mac this is sufficient for gamma correcting subpixel antialiased text. Gray antialiasing should not be gamma corrected on Mac. On Windows, the user can potentially set the gamma value to anything between 1.0 and 2.2 (or something like that). We support anything that resembles 1.0 closely enough by pushing the text out without any correction (like before). We also support anything that resembles 2.1 (the gamma hardcoded in GL's SRGB extension) by turning on the extension before blending the text. In between the two, we'll use gray antialiasing to avoid differing too much from the raster engine (which is our reference in this.) For gray antialiasing on Windows, we use a constant gamma of 2.3 which has been determined by experimentation. Since this is close enough to 2.1 we do gamma correction with SRGB extension. The distance limit of 0.2 is determined by some experimentation. Reviewed-by: Samuel (cherry picked from commit 79ba7cceca5e4029876ace2121edd25b08ae14ce)
