mutter-window: stream raw updates to ClutterX11TexturePixmap This changes the way we handle Damage events so instead of getting an event when the damage region of a pixmap becomes non-empty we now get sent all damage rectangles and stream those all though to ClutterX11TexturePixmap using clutter_x11_texture_pixmap_update_area() For Clutter 1.2, ClutterGLXTexturePixmap was updated so that calls to clutter_x11_texture_pixmap_update_area are now cheap (glXBindTexImageEXT calls are now deferred until just before painting) and since ClutterGLXTexturePixmap is now capable of queueing clipped redraws that can result in only updating a sub-region of the stage during a repaint cycle (and using glXCopySubBufferMESA to present the sub-region redraw to the front buffer) this should improve performance and reduced power consumption for a range of use cases. (For example viewing a website that has animated adverts doesn't force the whole screen to be redrawn for each frame of the advert) Besides being able to take advantage of glXCopySubBuffer to only update a small region of the stage the fact that this patch makes Mutter now request RawRectangles from the X server means we no longer do a synchronous X request for a complete Damage Region for every window damaged each frame. This should also improve performance. CLUTTER_PAINT=redraws can be used to visualize what parts of the stage are redrawn and with this patch applied I can open a terminal and as I type I see that only the damaged areas of the terminal are being redrawn.

Simplify relationship between mapping and visibility Previously, changes to the visibility of a window could be indicated by meta_compositor_map_window(), meta_compositor_unminimize_window(), meta_compositor_set_window_hidden(), etc, with the exact behavior depending on the 'live_hidden_windows' preference. Simplify this so that visibility is controlled by: meta_compositor_show_window() meta_compositor_hide_window() With an 'effect' parameter provided to indicate the appropriate effect (CREATE/UNMINIMIZE/MINIMIZE/DESTROY/NONE.) The map state of the window is signalled separately by: meta_compositor_map_window() meta_compositor_unmap_window() And is used only to control resource handling. Other changes: * The desired effect on show/hide is explicitly stored in MetaWindow, avoiding the need for the was_minimized flag. At idle, once we calculate the window state, we pass the effect to the compositor if it matches the new window state, and then clear the effect to start over for future map state changes. * meta_compositor_switch_workspace() is called before any windows are hidden or shown, allowing the compositor to avoid hiding or showing an effect for windows involved in the switch. http://bugzilla.gnome.org/show_bug.cgi?id=582341 * Handling of post-effect cleanups for MutterWindow are simplified - instead of trying to do different things based on the individual needs of different effects, we just wait until all effects complete and sync the window state to what it should be. * On unmap, once we destroy the pixmap, we tell ClutterX11Pixmap that we've done so, so it can clean up and unbind. (The unbinding doesn't seem to be working properly because of ClutterGLXPixmap or video driver issues.) http://bugzilla.gnome.org/show_bug.cgi?id=587251

mutter-window: stream raw updates to ClutterX11TexturePixmap This changes the way we handle Damage events so instead of getting an event when the damage region of a pixmap becomes non-empty we now get sent all damage rectangles and stream those all though to ClutterX11TexturePixmap using clutter_x11_texture_pixmap_update_area() For Clutter 1.2, ClutterGLXTexturePixmap was updated so that calls to clutter_x11_texture_pixmap_update_area are now cheap (glXBindTexImageEXT calls are now deferred until just before painting) and since ClutterGLXTexturePixmap is now capable of queueing clipped redraws that can result in only updating a sub-region of the stage during a repaint cycle (and using glXCopySubBufferMESA to present the sub-region redraw to the front buffer) this should improve performance and reduced power consumption for a range of use cases. (For example viewing a website that has animated adverts doesn't force the whole screen to be redrawn for each frame of the advert) Besides being able to take advantage of glXCopySubBuffer to only update a small region of the stage the fact that this patch makes Mutter now request RawRectangles from the X server means we no longer do a synchronous X request for a complete Damage Region for every window damaged each frame. This should also improve performance. CLUTTER_PAINT=redraws can be used to visualize what parts of the stage are redrawn and with this patch applied I can open a terminal and as I type I see that only the damaged areas of the terminal are being redrawn.

mutter-window: stream raw updates to ClutterX11TexturePixmap This changes the way we handle Damage events so instead of getting an event when the damage region of a pixmap becomes non-empty we now get sent all damage rectangles and stream those all though to ClutterX11TexturePixmap using clutter_x11_texture_pixmap_update_area() For Clutter 1.2, ClutterGLXTexturePixmap was updated so that calls to clutter_x11_texture_pixmap_update_area are now cheap (glXBindTexImageEXT calls are now deferred until just before painting) and since ClutterGLXTexturePixmap is now capable of queueing clipped redraws that can result in only updating a sub-region of the stage during a repaint cycle (and using glXCopySubBufferMESA to present the sub-region redraw to the front buffer) this should improve performance and reduced power consumption for a range of use cases. (For example viewing a website that has animated adverts doesn't force the whole screen to be redrawn for each frame of the advert) Besides being able to take advantage of glXCopySubBuffer to only update a small region of the stage the fact that this patch makes Mutter now request RawRectangles from the X server means we no longer do a synchronous X request for a complete Damage Region for every window damaged each frame. This should also improve performance. CLUTTER_PAINT=redraws can be used to visualize what parts of the stage are redrawn and with this patch applied I can open a terminal and as I type I see that only the damaged areas of the terminal are being redrawn.

mutter-window: stream raw updates to ClutterX11TexturePixmap This changes the way we handle Damage events so instead of getting an event when the damage region of a pixmap becomes non-empty we now get sent all damage rectangles and stream those all though to ClutterX11TexturePixmap using clutter_x11_texture_pixmap_update_area() For Clutter 1.2, ClutterGLXTexturePixmap was updated so that calls to clutter_x11_texture_pixmap_update_area are now cheap (glXBindTexImageEXT calls are now deferred until just before painting) and since ClutterGLXTexturePixmap is now capable of queueing clipped redraws that can result in only updating a sub-region of the stage during a repaint cycle (and using glXCopySubBufferMESA to present the sub-region redraw to the front buffer) this should improve performance and reduced power consumption for a range of use cases. (For example viewing a website that has animated adverts doesn't force the whole screen to be redrawn for each frame of the advert) Besides being able to take advantage of glXCopySubBuffer to only update a small region of the stage the fact that this patch makes Mutter now request RawRectangles from the X server means we no longer do a synchronous X request for a complete Damage Region for every window damaged each frame. This should also improve performance. CLUTTER_PAINT=redraws can be used to visualize what parts of the stage are redrawn and with this patch applied I can open a terminal and as I type I see that only the damaged areas of the terminal are being redrawn.

mutter-window: stream raw updates to ClutterX11TexturePixmap This changes the way we handle Damage events so instead of getting an event when the damage region of a pixmap becomes non-empty we now get sent all damage rectangles and stream those all though to ClutterX11TexturePixmap using clutter_x11_texture_pixmap_update_area() For Clutter 1.2, ClutterGLXTexturePixmap was updated so that calls to clutter_x11_texture_pixmap_update_area are now cheap (glXBindTexImageEXT calls are now deferred until just before painting) and since ClutterGLXTexturePixmap is now capable of queueing clipped redraws that can result in only updating a sub-region of the stage during a repaint cycle (and using glXCopySubBufferMESA to present the sub-region redraw to the front buffer) this should improve performance and reduced power consumption for a range of use cases. (For example viewing a website that has animated adverts doesn't force the whole screen to be redrawn for each frame of the advert) Besides being able to take advantage of glXCopySubBuffer to only update a small region of the stage the fact that this patch makes Mutter now request RawRectangles from the X server means we no longer do a synchronous X request for a complete Damage Region for every window damaged each frame. This should also improve performance. CLUTTER_PAINT=redraws can be used to visualize what parts of the stage are redrawn and with this patch applied I can open a terminal and as I type I see that only the damaged areas of the terminal are being redrawn.
