Martin Gräßlin	0cbc79193b	Do not use stackingOrder in LanczosFilter to get all EffectWindows LanczosFilter tries to discard all cached textures in the timer event by getting the stacking order and iterating over it. But this approach seems wrong from several aspects. First of all the xStackingOrder does not include Deleted windows. So if a cached texture still exists on an EffectWindow for a Deleted it would not be discarded. Also the xStackingOrder could result in an update from X because the stacking order is currently considered dirty. Last but not least the EffectsHandler::stackingOrder creates a temporary list of EffectWindows - good for Effects but not necessarily useful inside KWin core. Instead the LanczosFilter gets the list of Clients, desktops, unmanaged and deleted and iterates over them to check whether there is a texture to discard. REVIEW: 109954	13 years ago

Martin Gräßlin	c3ec860a72	Drop ARB shader code path from Lanczos Filter Since color correction got pushed merged in the Lanczos Filter is only created for OpenGL2. Which means the complete ARB shader code path has been dead since 4.10 anyway. REVIEW: 108856	13 years ago

Martin Gräßlin	987bc837d9	Remove define KWIN_HAVE_OPENGL_COMPOSITING Due to changes in build system we have always either OpenGL or OpenGL ES. This allows to remove the KWIN_HAVE_OPENGL_COMPOSITING define. In the effects the define is kept as KWIN_HAVE_OPENGL which can be used in future to build also an XRender only effect system.	15 years ago

Martin Gräßlin	6270b502ba	ARB Shader fallback to Lanczos filter. This allows using Lanczos filter also on systems not supporting GLSL. See http://svn.reviewboard.kde.org/r/5777/ svn path=/trunk/KDE/kdebase/workspace/; revision=1195273	16 years ago
Martin Gräßlin	3e689ff201	Cache generated Lanczos textures. This provides a significant performance improvement especially for Present Windows. Whenever a lanczos resampling is done the resulted texture is cached, till the window is damaged or a texture of different size is required. This means that for a taskbar thumbnail the resampling only occurs once unless the window is damaged and for present windows it only occurs when the windows are resized and then only after the windows have already been moved. Highlighting windows does not cause a resampling any more. See review request http://svn.reviewboard.kde.org/r/5708/ svn path=/trunk/KDE/kdebase/workspace/; revision=1191874	16 years ago
Fredrik Höglund	119c06e403	Make the lanczos shader use a fixed number of iterations in the loop. This makes it possible for the GLSL compiler to unroll it, which also avoids the need to use relative addressing. With this change the shader should hopefully work with the R300G driver. The unused kernel weights are set to zero so they don't contribute to the end result. Thanks to Tom Stellard and Marek Olšák for their suggestions on how to solve this problem.
