For text rendering in Qt Quick, we currently have the limitation that when rendering text at such a large size that the distance fields start showing artifacts, the only option is to use NativeRendering, which will look nice, but which will use a lot of texture memory for the glyph cache, since it will actually cache the glyphs at the requested size. A suggested approach would be to fall back to using triangulated paths when the font gets large enough, but the work on this was never completed. It turns out that we can get this now, basically for free, since we already support rendering arbitrary QPainterPaths using Qt Quick Shapes. The only thing missing is the ability to add the path of a given text to the shape. This patch fills in that gap. Note that this is currently not supported by nvidia renderer. [ChangeLog][QtQuick] Added PathText path element which can be used together with Qt Quick Shapes to get text rendering that does not cache glyphs in a texture, but triangulates the outlines of the glyphs instead.

README
The Qt Quick module provides the basic elements to specify and implement your user interface declaratively, using the Qt Meta-Object Language (QML). The Qt QML module provides the engine and language infrastructure for QML itself. This language is very expressive and human readable, and can be used by designers to actually implement their UI vision. QML UIs can integrate with C++ code in many ways, including being loaded as a part of a C++ UI and loading data models from C++ and interacting with them. Mostof these examples can be viewed directly with the QML viewer utility, without requiring compilation. Documentation for these examples can be found via the Examples link in the main Qt documentation.
