* Adapt Qt Quick 2 renderer to work with OpenGL Core ProfileSean Harmer2013-11-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The basic approach is to have the batched renderer create and bind a vertex array object if it detects we are using an OpenGL Core profile context. The VAO is bound for the duration of the QQ2 renderer's work cycle and unbound at the end so as to not interfere with any other VAO's a user may wish to use. All shaders have been copied and ported to be compliant with the GLSL 150 core specification which is the minimum for a Core profile context (OpenGL 3.2 Core). We are not using any newer features as yet so this will work anywhere we can get a Core profile context. The QSGShaderSourceBuilder class has been extended to resolve any requests for shaders to the same basefilename with "_core" appended prior to any file extension. This could be extended in the future to allow version, or GPU or platform specific shaders. The QSGShaderSourceBuilder has also been extended to allow it to insert #define definitions in the prologue of a shader. Any such definition is inserted: * After the last #extension directive (if any are found) * Otherwise after the #version directive (if found) * Otherwise at the start of the shader source This is required by the custom particle shaders which make extensive use of such #defines. In addition the mechanism used by the distance field glyph cache to extend the cache with new glyphs has been modified to work (and work more efficiently) when using a Core profile context. Rather than using a shader program and a buffer filling quad to blit the old texture into the new cache texture, we instead use the technique of framebuffer blitting. The existing fallback implementation using glTexSubImage2D() is still available if needed. The DECLARATIVE_EXAMPLE_MAIN macro has been extended to allow easy testing of any of the QtDeclarative examples with a core profile context. Just run the example with QT_QUICK_CORE_PROFILE=1 ./text for e.g. The only ones that may not work out of the box are those that provide GLSL shader source e.g. the customparticles or shader effect examples. These work fine if the shader source is adapted to GLSL 150 core. In the future it may be a good idea to expose some context property to QML that the user can use to determine what shader source variation to provide to Qt Quick. Along these lines it would also be very nice to allow the provision of shader source to ShaderEffect or CustomParticle from a separate source file just as we now do within Qt Quick.

* Use one render loop per QQuickWindowGunnar Sletta2013-10-301-2/+3
| | | | | | | | | | | | | | | | | | | See the task for the full reasoning behind this patch. The threaded renderloop has been refactored to have one window per thread. This is mostly a simplification of the current code path where for loops over multiple windows are turned into if (window). The QSGContext has been split into two classes, QSGRenderContext for which there is one per OpenGLContext. The rest of the patch is name changes and a couple of cleanups in the hopes of simplifying this change.

* Updated distance field glyph caches to use QDistanceField.Yoann Lopes2013-08-271-9/+7
| | | | | | | | | | | | | | Some OpenGL drivers assume alpha-only images are always tightly packed, regardless of what is set for GL_UNPACK_ALIGNMENT. We now use QDistanceField to store glyphs, which aligns scanlines on a 1-byte boundary, instead of QImage which uses a 4-byte boundary. A previous workaround uploaded scanlines one at a time, but this is also broken with some other drivers...

* Fix memory leak with the shared distance field glyph cache.Andrew den Exter2012-03-141-4/+15
| | | | | | | | | | | | | | | | | A new glyph node instance registers its owner element with its glyph cache which in the case of the shared distance field glyph cache connects a signal from the cache to a slot on the owner, changing the text creates a new node but destroying the old node didn't remove the connection causing them to accumulate over time. In the glyph node; unregister the owner element from the cache on destruction, and in the cache only connect an owner element the first time it is registered and keep a reference count so the items can be disconnected when registrations from all nodes have been cancelled.

* Fix missing glyphs when using shared distance-field cacheEskil Abrahamsen Blomfeldt2012-03-061-14/+21
| | | | | | | | | | | | | | | | | | | | | | When using a shared distance field cache, signals such as itemsMissing() and itemsUpdated() can be triggered in the server process by external requests. This, in turn, can lead to unnecessary storeGlyphs() calls (performance hit) and, even worse, calls to setGlyphPositions() for glyphs which have not previously been requested through populate(). The latter could cause missing glyphs when the same characters were requested later, as they would then be stored in the cache with the bounding rect of a default constructed QPainterPath (in setGlyphPositions()). To fix this, we ignore all glyphs which have no been requested in this process, thus filtering out all events for glyphs which have only been used externally so far. I've also added an assert to the setGlyphPositions() to help us catch this case early if it should return.

| * Avoid unnecessary updates when using in-process cacheEskil Abrahamsen Blomfeldt2012-03-011-5/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever an in-process cache is updated, it will emit itemsAvailable() signals to all listening glyph caches. This will in turn cause each of the glyph caches to update and each of the glyph nodes to be preprocessed (the entire scene graph will be updated.) This happens even if the changes to the in-process cache are requested by an external client, due to a cross-process cache sharing mechanism. However, itemsAvailable() signals are only interesting if the items were requested by the in-process cache. We therefore add a mechanism now to check if the glyphs were actually requested by the cache before updating anything.
