* Add support for color glyphs (Emoji) on Mac OS X and iOSTor Arne Vestbø2013-02-131-12/+28
| | | | | | | | | | | | | A new glyph type is added to the glyph caches for ARGB bitmap glyphs, and the raster and OpenGL paint engines have been modified to support this glyph type for drawCachedGlyphs(). The CoreText font engine implements support for these glyphs through the CTFontDrawGlyphs API, since CGContextShowGlyphsWithAdvances does not handle color glyphs.

* Don't assume m11/m22 represents the scale of a QTransformTor Arne Vestbø2013-01-241-1/+7
| | | | | | | | | | | | We can still assume it when pulling out the scale of the glyph cache, since we limit it to scaling, but when computing the scale from the current matrix we have to decompose it. We always use a positive scale in the glyph-cache, and let the drawing code take care of any flipping of the coordinates.

* | Add support for retina glyph-based text drawing in the GL paint-engineTor Arne Vestbø2013-01-211-9/+25
| | | | | | | | | | | | | | | | | | | | Instead of always using a non-transformed glyph-cache we now allow a scaled glyph-cache so that retina-screens can take advantage of this. We take the cache's scale into account when positioning and drawing the glyphs so that the scale is not applied twice.

| * Don't assume QSurfaceFormat's stencil buffer size is >= 0Tor Arne Vestbø2013-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The value -1 is used to indicate no stencil buffer, so we have to check for sizes <= 0 when deciding whether or not to triangulate the path in QOpenGL2PaintEngineExPrivate::fill(). This fixes an issue where filling a path would end up filling the whole outline of the path, which was very visible with fonts over a certain size (when we go from using the glyph cache to drawing filled paths for each glyph).

* | Refactor paint/font-engine shouldDrawCachedGlyphs and supportsTransformationsTor Arne Vestbø2013-01-101-11/+12
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some cruft had built up over time, and this is an attempt at cleaning up the naming and use of these functions, and should not have any behavioral effects. The function supportsTransformations() has been renamed in QPaintEngineEx to reflect its use, which is to decide if QPainter needs to pre-transform the coordinates of the static text before asking the paint-engine to draw it. The new name is requiresPretransformedGlyphPositions(). The OpenGL and CoreGraphics (Mac) paint engines keep their behavior of not needing pre-transformed text, while the raster engine needs this when using cached glyphs. The base-class implementation assumes that all transforms that include a projection will need pre-transform, which is also the case for the raster engine. All decisions in the paint engines about whether or not to use the glyph cache when drawing text are now deferred to the function shouldDrawCachedGlyphs(), which has been refactored for the GL paint engine(s) to share more logic. All implementations call the base class implementation, which ensures that large font sizes will not be cached. The raster engine will in addition ask the font engine whether or not it can produce glyphs for the glyph-cache with the given transform. This is the only remaining instance of the supportsTransformations() function, and will for all font engines except the CoreText engine support affine transformations. The CoreText engine on the other hand only supports translations (for now).

| | | | | | | | | | | | | | There are a lot of hacks here and there in Qt trying to align the text in a correct way which caused regressions to appear once the default coordinate system changed.

* OpenGL: Use official glext.h and gl2ext.h headersSean Harmer2012-08-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Khronos group makes the glext.h (Desktop OpenGL) and gl2ext.h (OpenGL ES2) headers officially available nowadays. Most (all?) Linux systems ship this by default. On Windows platforms the glext.h file needs to be downloaded from http://www.opengl.org/registry/api/glext.h and placed alongside the system OpenGL header. Making use of the official header reduces the maintenance overhead for OpenGL support in Qt by removing the need to copy and paste definitions into the Qt sources. As the Khronos-provided headers are standardised and backwards and forwards compatible we can utilise these for all platforms rather than just for Windows. This means that all definitions required by Qt will be present even if the system ships out-dated equivalents. Mac OS X needs special handling in that we should always use the system-provided headers there. This is because Apple controls the OpenGL driver and the headers that go along with it. As such there is no possibility that the driver exposes additional functionality compared with the system-provided OpenGL headers. Apple has also decided to make different decisions about some OpenGL typedefs compared to other implementations. For example, Apple typdefs GLhandleARB to void* whereas other platforms use unsigned int. The alternative, which is to use the system provided glext.h (or gl2ext.h) header means that Qt code would need to check for the availability of such definitions wherever it is not guaranteed to be provided by core OpenGL/ES just to compile. The proposed approach means that Qt can compile regardless of the system's OpenGL extension support. We just need to be rigourous in runtime checking of support for extensions but that is already a requirement (and is missing in a few places, see TODO's added in this commit). The official Khronos headers are added to Qt as qopenglext.h - Desktop OpenGL qopengles2ext.h - OpenGL ES2 They need to be public but not part of QtGui module include, hence the headers have been modified by adding #if 0 #pragma qt_no_master_include #endif to them. This has been tested on: Gentoo Linux with GCC 4.6.3 Windows 7 with MSVC 2010 Mac OSX 10.8 with Apple clang 4.0 (based on LLVM 3.1svn) QNX with qcc (based on GCC 4.4) A small change is needed to QtDeclarative when building for OpenGL ES 2 after applying this commit.
