* Make QtOpenGL compile on OpenGL ES 1.1 againTom Cooksey2009-05-141-2/+2

* Enabled compilation of both GL and GL2 paint engine.Samuel Rødal2009-05-131-11/+11
| | | | | | | Compile both GL and GL2 paint engine on desktop, and choose between them at run-time based on GL version flags. Reviewed-by: Tom
* Big GL Extension CleanupTom Cooksey2009-05-061-2/+3
| | | | | | | | | Clean up the extension naming and make things build on OpenGL ES 2.0 again. All the extensions which made it into OpenGL 2.0 spec have have the EXT postfix removed. This also eliminates defines on ES 2.0 as the code now refers to the in-spec names. Reviewed-by: sroedal
* Make useCorrectShaderProg() return a bool againTom Cooksey2009-04-221-3/+1
| | | | | Returns true if it had to change the shader program so the engine knows it needs to clean the uniforms.

| * Smudgy text in GL2 paint engine when drawing on non-integer offsets.Samuel Rødal2009-04-171-21/+39
| | | | | | | | | | | | | | | | | | Special-case TextDrawingMode in updateMatrix() as we know that we'll have a pure translating transform, and round the transform's dx and dy to avoid drawing on non-integer offsets. Task-number: 245806 Reviewed-by: Tom
| * Correctly handle using GL pixmaps that still have an active engine.Samuel Rødal2009-04-171-2/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the case where a GL pixmap is used when there it still has an active engine we need to ensure that the pixmap has been flushed from the render FBO first. The newly added QGLPixmapData::copyBackFromRenderFbo() handles this. In addition, because several GL 2 paint engines can be active on the same context at the same time, we can't make any assumptions and need to call the newly added QGL2PaintEngineEx::ensureCreated() in the beginning of any state-dependent paint engine function. QGL2PaintEngineEx::ensureCreated() correctly transfers control to the current engine if a different engine is active. Running lance with -pixmap and -graphicssystem opengl works correctly with the GL pixmap backend now.
| * Use FBOs as pixmap backend in GL graphics system.Samuel Rødal2009-04-161-1/+37
| | | | | | | | | | | | | | | | We now use FBOs to implement render-to-pixmap for the GL pixmap backend. A multisample FBO is used for rendering, and is then blitted onto a non-multisample FBO dynamically bound to the relevant texture. Reviewed-by: Tom
| * GL2: Avoid expensive updateDepthClip() every time setState() is calledSamuel Rødal2009-04-161-16/+14
| | | | | | | | Only call updateDepthClip() if the clip has actually changed.
* | Make text rendering work again on the GL2 engineTom Cooksey2009-04-211-41/+44
| | | | | | | | | | - But now it can handle non-solid-color pens, the whole reason for the refactor in the first place.

| | | | | | RevBy: Trond Details: Need to make sure clipping/scissoring etc is turned off and that we are in a good state.

* Fixes: Introduce mode transfer functions in the GL 2 paint engine.Samuel Rødal2009-04-011-51/+92
| | | | | | | | RevBy: Tom Details: Mode transfer lets us optimize the case where the same operation is done a lot of times in a row, for example image or text drawing, by being able to assume that most of the state has already been set up properly.
* Fixes: GL 2 paint engine text rendering optimization.Samuel Rødal2009-04-011-56/+45
| | | | | | | RevBy: Tom Details: Buffer vertex and texture coordinates so that we get away with just a single glDrawArrays call per text item. Also move drawCachedGlyphs() into the private class.
* Fixes: Improve text rendering in GL 2 paint engine.Samuel Rødal2009-04-011-2/+2
| | | | | Details: Avoid adding 0.5 to dx() / dy() which caused images / glyphs to get slight antialiasing and edge artifacts.
