| * Restore smooth-scaled drawing of 0.5x-2.0x scaled glyphs in the GL engineTor Arne Vestbø2013-07-081-12/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b5922c89ba942 (Add support for retina glyph-based text drawing in the GL engine), and commit 155a20628b91 (Use QPaintEngineEx to decide if font is too big for using the glyph cache) together changed the behavior of drawing scaled cached glyphs in the GL engine, producing blocky text drawing when using the FreeType font engine. Whereas before we would cache all glyphs without any transform, and let the paint engine take care of the transform, commit b5922c added support for a scaled GL glyph cache, resulting in a 2x cache, drawn at 1x for example. The problem was that the FreeType engine claimed to support producing glyphs at 2x, but did that using the QFontEngine baseclass implementations, which use a simple fast-transform to scale up the glyphs. The result was a 2x cache with horrible looking glyphs. The first step in fixing this issue was to have the FreeType engine claim to only support translations. This would then make the paint engine choose path-based drawing for all scaled text, which is slow. To restore the optimization that we would draw 0.5x-2.0x scaled text using a smooth-scale in the GL engine (which was removed in 155a206), we then needed to extend shouldDrawCachedGlyphs() and add a special condition for this, coupled with a bit of logic in drawCachedGlyphs() that ensures we don't propagate the painter scale to the glyph cache if the engine is not able to produce scaled glyphs for it. This means we get the old behavior of the GL engine doing a smooth scale of the 1x glyph in the cache. Finally, since the raster engine also checks if the font engine supports the current transform, but for FreeType then ends up in a separate code path when actually drawing the glyphs (as the FreeType font engine supports internal glyph caching), we need to add a corresponding check for hasInternalCaching() in the shouldDrawCachedGlyphs() function, now that the FreeType engine only reports that it supports translations.

* Add default value for qHash's 'seed' argument for QOpenGLVersionProfile/StatusTor Arne Vestbø2013-04-151-1/+1
| | | | | | | | | | | | | | | | Although template<typename T> inline uint qHash(const T &t, uint seed) from qhash.h is never instantiated because we have the two-argument version of qHash() for both QOpenGLVersionProfile and QOpenGLVersionStatus, we need the default argument, as the template in qhash.h uses noexcept, which is evaluated regardless of instantiation, and uses qHash(t) without a seed. This behavior seems to not be the case with Apple clang 4.2, but has been observed with Apple clang 4.1, Clang 3.2, and GCC 4.8.
