In systems with bamfdaemon running, windows get this property for finding the dekstop spec file of an application. This can be used to find the defined icon for any application window that reports this attribute and provider much better icon matching.
Looking up GDesktopAppInfo from the GTK Application ID we can get a much better match for the icon and load it at the appropriate scale. This results in matching icons to straneous windows and better looking icons overall.
Enabling code that is supposed to be used in compositing conditions is harmful if compositing is not actually available. Just checking the preference is not enough to make sure that compositing is available - the X server might be missing crucial extensions for compositing to work, which in turn correctly disables the internal compositor. The end result is graphical issues like black borders around windows in such situations. Make sure that compositing is both requested AND available to fix this bug.
Some files do not report their application icons correctly in the window properties. This patch allows the marco UI to search for the corresponding .desktop file and render the icon in the desktop info on both the alt-tab popup and the window mini-icon.

An ARGB window with a frame is likely something like a transparent terminal. It looks awful (and breaks transparency) to draw a big opaque black shadow under the window, so clip out the region under the terminal from the shadow we draw. Add meta_window_get_frame_bounds() to get a cairo region for the outer bounds of the frame of a window, and modify the frame handling code to notice changes to the frame shape and discard a cached region. meta_frames_apply_shapes() is refactored so we can extract meta_frames_get_frame_bounds() from it. https://bugzilla.gnome.org/show_bug.cgi?id=635268 NOTE: Applied only partially, compositor part is still missing... upstream commit: https://gitlab.gnome.org/GNOME/metacity/commit/0f2e32d1
This method allows forcing a style update of a particular frame from the core, so that it can pick up style variants. https://bugzilla.gnome.org/show_bug.cgi?id=645355 upstream commit: https://gitlab.gnome.org/GNOME/metacity/commit/97554dc4
There were actually *two* MetaFrameGeometry structs: one in theme-private.h, one in frame.h. The latter public struct was populated by a mix of (void*) casting and int pointers, usually pulling directly from the data in the private struct. Remove the public struct, replace it with MetaFrameBorders and scrap all the pointer hacks to populate it, instead relying on both structs being used in common code. This commit should be relatively straightforward, and it should not do any tricky logic at all, just a sophisticated find and replace. https://bugzilla.gnome.org/show_bug.cgi?id=644930 upstream commit: https://gitlab.gnome.org/GNOME/metacity/commit/72224a165 NOTE: Patch copied from metacity and adapted for marco.
This way the xserver never paints the frame background, even if the client window is destroyed. This allows us to have clean destroy window animation. There is no problem with interactive resizing because applications are using the XSync protocol, so we're not painting unless the client has redrawn. https://bugzilla.gnome.org/show_bug.cgi?id=734054 origin commit: https://gitlab.gnome.org/GNOME/metacity/commit/78c283c
