| * | Move the 0.5 offset we add for aliased rendering to updateMatrix()Tom Cooksey2009-12-282-33/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old code set and unset a temporary matrix for every draw command when doing aliased rendering. Instead, we just use a flag to indicate that updateMatrix() should add the offset. This means the offset is added only once. When doing lots of small rendering operations on a (non-multisampled) QGLWidget, this gives up to 72% performance boost on the SGX. Reviewed-By: Kim

| | * | Fix text rendering on GL2 paint engineTom Cooksey2009-12-232-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you draw with a brush, then draw a pixmap, then draw with the same brush, the GL2 engine wouldn't update the fragment shader to use the brush. This is because it detected the brush hadn't changed and so didn't need updating. To fix this, we now set the current brush to noBrush when drawing an image/pixmap so the engine knows it needs to update the GL state for the brush. Reviewed-By: Kim

| * | Use 3x3 PMV matrices rather than 4x4 in the GL2 engineTom Cooksey2009-12-223-64/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QGraphicsView based applications will set a new transform for every item before it's painted. This leads to lots of updates to the PMV matrix. So switching to a 3x3 rather than a 4x4 gives us less data to pass to GL for each QGraphicsItem which gets rendered. It also means the vertex shader is more efficient. However, this patch only gives a maximum 2.5% speed improvement on the SGX, which seems to be only due to the faster vertex shader rather than the reduced amount of data we pass to GL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the triangulating stroker, the last point was being duplicated in dashed paths. But because QDataBuffer::add() takes a ref to a float rather than a float, it would resize the data buffer and then try to fetch the values out of a pointer to the original buffer memory. This change copies the values into temporary variables before resizing the array. Task-number: QTBUG-6045 Reviewed-by: Sarah Smith

| * | Fix EGL surface leaks when re-parenting QGLWidget on X11/EGLTom Cooksey2009-12-154-13/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a QGLWidget is re-parented, it's native X11 window usually gets destroyed and re-created. This also happens when you set a window attribute or flag. On EGL, we must destroy the surface for the window before destroying the window itself, otherwise we can leak the surface. This also fixes lots of BadDrawable errors when running the autotests (which were due to surface leaks!). Reviewed-By: TrustMe
