* 12to11.c (MakeColormap): Delete function. (XLMain): Stop making colormap here. * compositor.h (ImmediateRelease): New flag. (struct _BufferFuncs): New field can_release_now. (struct _State): New flag `BufferAlreadyReleased'. * egl.c (struct _CompositeProgram): New field `invert_y'. (EglCompileCompositeProgram): Get new uniform index. (Composite): Apply InvertY. (egl_render_funcs): Set ImmediateRelease flag. (BufferFromDmaBuf): Set InvertY flag if set. (UpdateTexture, UpdateShmBufferIncrementally): Set CanRelease flag on SHM buffers. (UpdateBuffer): Don't update if damage is empty. (CanReleaseNow): New function. (egl_buffer_funcs): Add CanReleaseNow. * picture_renderer.c (MakeCheckWindow): New function. (FindSupportedModifiers): Use a more similar window to look for modifiers. (CanReleaseNow): New function. (picture_buffer_funcs): Add CanReleaseNow. * renderer.c (RenderCanReleaseNow): New wrapper function. (InstallRenderer): Create colormaps here, so the buffer init function can get it. * shaders.txt (Composite Rectangle Fragment Shader RGBA) (Composite Rectangle Fragment Shader RGBX) (Composite Rectangle Fragment Shader External): New uniform `invert_y'. (main): Use it. * subcompositor.c (SubcompositorUpdate): Always update attached buffer from damage, even if damage is empty. * surface.c (TryEarlyRelease): New function. (InternalCommit): Call it. Also, do not call role release_buffer hook if ImmediateRelease is specified by the renderer. (SavePendingState): Likewise, release buffers immediately if possible.
