* Made fast blur in GL 2 engine be radius independent.Samuel Rødal2009-09-242-140/+97
| | | | | | | | | | | This is useful when animating the blur radius, as you don't want to suffer the hit of compiling / linking a new shader program for each radius the first time the animation is played. Also use the fast blur when the radius is 5 or below, as the quality difference is insignificant. Reviewed-by: Rhys Weatherley

* Optimized GL2 engine to use scissor clipping more aggressively.Samuel Rødal2009-09-212-95/+72
| | | | | | | | | | | | | | | | There's no reason to stop using a scissor clip when a more complex clip is set. Instead, we can use a combination of scissoring and depth clipping to represent the final clip. When intersecting with a new clip path, if the clip path is a rectangle we simply intersect it against the scissor clip, and otherwise we intersect its bounding rect against the scissor clip and write the actual path to the depth buffer. The patch simplifies the logic in clip() quite a bit, except in the UniteClip case in which we don't care about performance anyways. It also fixes a bug which could cause rendering errors if the stencil buffer contains junk before painting. Reviewed-by: Gunnar Sletta

* Refactored gl window surface a bit.Gunnar Sletta2009-09-211-37/+43
| | | | | | | | | | | | The logic was a bit messy and didn't work on Mac OS X. On Linux we also had issues with 8xxx nvidia cards which didn't render properly. The FBO is now unbound between calls to beginPaint(), which prevents other gl calls from messing it up, which is probably what was the error in the first place. In addition, on Mac OS X, we also call the upatePaintDevice() as a result of setGeometry() to force-update the dimensions of the context. Reviewed-by: Trond
* Performance: reduce overhead of updateMatrix() in GL2 paint engineRhys Weatherley2009-09-211-32/+45
| | | | | | | | | | | The original code was performing 40 floating-point multiplications, 40 additions, and 2 divisions every time the matrix was changed. Because most of the components in the orthographic projection matrix are trivial, we can implement the same transformation with only 6 multiplications, 6 additions, and 2 divisions.

E.g. examples/widgets/wiggly links against QtGui. QtGui links against libEGL.so. Therefore, when you link wiggly, the linker has to be able to find libEGL.so, even though wiggly doesn't use EGL directly. To facilitate this, -Wl,rpath-link=/path/to/egl needs to be added to QMAKE_PRL_LIBS in libQtGui.prl and -Wl,rpath-link=/path/to/gl needs to be added to QMAKE_PRL_LIBS in libQtOpenGL.prl. This only needs to be done when the EGL/GL libs are not in the default search directories. As the paths will also change depending on the mkspec, two new variables have been added: QMAKE_LFLAGS_EGL & QMAKE_LFLAGS_OPENGL. These can be set in the mkspec and will be added to the relevent prls. E.g. QMAKE_LFLAGS_EGL += -Wl,-rpath-link=$${QMAKE_LIBDIR_EGL} QMAKE_LFLAGS_OPENGL += -Wl,-rpath-link=$${QMAKE_LIBDIR_OPENGL} Reviewed-by: Marius Storm-Olsen

| * Reduce overhead of paint engine-specific pixmap filtersRhys Weatherley2009-09-164-19/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Engine-specific pixmap filters were being created, used, and destroyed every time draw() was called on QPixmapColorizeFilter, QPixmapBlurFilter, and so on. This had a heavy performance penalty and made it difficult for the GL paint engine to cache shaders from one request to the next. A generic filter can request an engine-specific filter that matches its parameters. The engine can either create a new one or return a previously allocated filter object. Ownership of engine-specific pixmap filter objects is moved to the paint engine itself.

| | | | | | | | | | | | | | | | | | | | The setTextureCoordsEnabled was enabled in two places, but never disabled causing it to always be used. When using a varying in a vertex shader and not using it again in the fragment shader this produces a warning, and rightly so. Since the property is 100% detectable based on the fragment shader used, move the logic into the shader selection code and kill the property all together. This should also speed up solid filling a bit...
