* Avoid loading and keeping unused fallback font enginesEskil Abrahamsen Blomfeldt2012-02-171-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | When we request glyphs from fallback fonts, we would potentially load all fonts on the system into memory. This is especially true for glyphs that are not supported by any font (or by the last in the list) in any "Common" script (which e.g. includes CJK). This would make any application which tried to display unsupported glyphs use huge amounts of memory for keeping unused fonts cached, only limited by the number of fonts on the system. The patch contains two solutions: First, before loading the font, the multi font engine will be asked whether it needs to be tried for the given character. By default, this will always be true, so all fonts will be tried, but with the new font config multi engine in the platform plugin, it will ask FontConfig whether the font contains a glyph for the character. Should the font be loaded and still fail to resolve the character (which could be the case for other platforms), we will simply delete it again immediately instead keeping it cached.

* Support adding application fonts with QFontconfigDatabaseJiang Jiang2011-09-231-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QFontDatabaseQPA should be able to reinitialize database and reregister all the fonts when an application font is added, because it will trigger db->invalidate(). Add cloneWithSize support to QFontEngineBox so that even no usable font is found in QFontDatabase, QRawFont::setPixelSize can still work (without making the result rawfont invalid). Register application fonts with QFontconfigDatabase, the code is adapted from QFontDatabaseX11. Reenable QRawFont tests for QPA, these usages are now supported in QPA. Fix QStaticText tests, raster in QPA does support transformations. Translate the text before ZAxix rotation so that it will be visible in canvas. Add back fixedPitch support to QPA, and fix QFontDatabase tests. Fix QGlyphRun tests, ignore non-existence glyphs in alphaMap locking. Fix QFontMetrics tests.

* Make QtQuick2 compile on QPAEskil Abrahamsen Blomfeldt2011-04-281-0/+10
| | | | | | | | | | | Moved the logic to set pixel size into the font engines to avoid making the platform plugin interface too complex, and added a function in QPA to make an isolated font engine based on font data. Currently none of the QPA back-ends supports it, but it compiles and spits out a warning if you try to create a QRawFont from data there. This isn't used in QtQuick2 anyway. Reviewed-by: Jiang Jiang
