Make shadows pretty and configurable The current shadow code just uses a single fixed texture (the Gaussian blur of a rectangle with a fixed blur radius) for drawing all window shadows. This patch adds the ability * Implement efficient blurring of arbitrary regions by approximating a Gaussian blur with multiple box blurs. * Detect when multiple windows can use the same shadow texture by converting their shape into a size-invariant MetaWindowShape. * Add properties shadow-radius, shadow-x-offset, shadow-y-offset, shadow-opacity to allow the shadow for a window to be configured. * Add meta_window_actor_paint() and draw the shadow directly from there rather than using a child actor. * Remove TidyTextureFrame, which is no longer used https://bugzilla.gnome.org/show_bug.cgi?id=592382

Make MetaShadowFactory public The basic MetaShadowFactory type is moved to a public header, while the functions to fetch and paint shadows are kept private. The public object will be used for configuration of shadows by plugins. https://bugzilla.gnome.org/show_bug.cgi?id=592382

Move the installed includes to a subdir If mutter is going to be a "real" library, then it should install its includes so that users can do #include <meta/display.h> rather than #include <display.h> So rename the includedir accordingly, move src/include to src/meta, and fix up all internal references. There were a handful of header files in src/include that were not installed; this appears to have been part of a plan to keep core/, ui/, and compositor/ from looking at each others' private includes, but that wasn't really working anyway. So move all non-installed headers back into core/ or ui/. https://bugzilla.gnome.org/show_bug.cgi?id=643959

Implement more accurate clipping of obscured shadows Instead of making optimizing obscured shadows an all-or-none operation, pass the clip region to meta_shadow_paint() and only paint the 9-slices that are at least partially visible. https://bugzilla.gnome.org/show_bug.cgi?id=592382

Only shadow ARGB windows with a frame outside the frame 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

Make window shadows globally configurable Instead of setting shadow parameters on individual windows, add the idea of a "shadow class". Windows have default shadow classes based on their frame and window type, which can be overriden by setting the shadow-class property. Each shadow class has separably configurable parameters for the focused and unfocused state. New shadow classes can be defined with arbitrary names. https://bugzilla.gnome.org/show_bug.cgi?id=592382
