* Don't issue GL calls when the geometry is emptyEskil Abrahamsen Blomfeldt2011-07-051-0/+2
| | | | | | | | | | | | | | | | | | | This works as a band-aid and optimization for QT-5104, because in the text in the example, which contains latin text and has a latin default font set, will think of all spaces between the cyrillic characters as latin characters, hence it will make separate text items for them and issue separate glDrawElements() calls. By cutting off if there are no glyphs to draw, we can avoid hitting the actual bug for this and several other use cases, making it less likely to happen.

* Refactor glyph pretransform checkJiang Jiang2011-06-031-0/+1
| | | | | | | | | | | | | | | Move paintEngineSupportsTransformations logic from QPainter to paint engine subclasses. Simplify and consolidate checks for cached drawing (pretransformed) and path drawing (untransformed) in raster paint engine. Fix unnecessary transform when paint engines actually take the path drawing track. Fix scaling and rotation transform in raster engine for Mac.

* Fall back to using paths for large fonts in drawStaticText()Eskil Abrahamsen Blomfeldt2011-05-181-11/+22
| | | | | | | | | | | | | | 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.

* Support gamma correction of text on GLEskil Abrahamsen Blomfeldt2011-05-031-2/+29
| | | | | | | | | | | | | | | | | | | | | | | | | 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)
