* | Use texture_from_pixmap on X11 & avoid copiesTom Cooksey2009-07-221-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch tries to use texture_from_pixmap extentions on glX to properly bind an X Pixmap to a texture in QGLContextPrivate::bindTexture(QPixmap,). Because GL & X have different coordinate systems, the pixmap will be inverted about the y-axis. The extension does however allow a GLX_Y_INVERTED_EXT attribute to be set which will bind the pixmap the correct way up. If the underlying driver doesn't support this, texture_from_pixmap can't be used for QGLContext::bindTexture, because that function expects the resulting texture to be the right way up. However, it can still be used internally by the paint engine for drawPixmap operations. For these cases, if the pixmap is inverted, the paint engine can simply invert the texture coords to compensate. This is why this patch also moves QGLTexture into qgl_p.h. QGLContextPrivate::bindTexture(QPixmap,) now returns a QGLTexture which the paint engine can inspect to see if it needs to invert the texture coords. Finally, it seems on some (probably all) drivers, deleting an X pixmap which has been bound to a texture before calling glFinish/swapBuffers renders garbage. Presumably this is because X deletes the pixmap behind the driver's back before it's had a chance to use it. To fix this, we reference all QPixmaps which have been bound to stop them being deleted and only deref them after we swap the buffer, when they can be safely deleted. Reviewed-By: Kim

* If EGL fails to provide a valid Visual ID, try XRender for ARGBsTom Cooksey2009-05-221-9/+55
| | | | | | | | | This patch is inspired by the "Fix ARGB visuals" patch in the Maemo branch. Thanks go to the author of that patch (who isn't signed up to Gitorious and thus can't be named - you know who you are! Thanks!!). This patch should also fix ARGB visuals (even if they are supplied by EGL) as such visuals require a colormap.
* Try to use the X11 visual ID provided by EGLTom Cooksey2009-05-221-30/+74
| | | | | | | EGL has an EGL_NATIVE_VISUAL_ID which can by used as the window's visual ID. We now try to use this ID to avoid an XVisual <-> EGLConfig mis-match. Of course this is usually broken in the EGL library, so we fall back to trying to match outselves.
