 want to read the document in reverse order, since the base features
 are discussed under version 1.

-New Features in Theme Format Version 3.4
-========================================
-
-An additional color type is added to pick up custom colors defined
-in the GTK+ theme's CSS:
-
-  gtk:custom(name,fallback)
-
-where <name> refers to a custom color defined with @define-color in
-the GTK+ theme, and <fallback> provides an alternative color definition
-in case the color referenced by <name> is not found.
-
-New Features in Theme Format Version 3.3
-========================================
-
-Add two additional button background functions - left_single_background and
-right_single_background - for button groups with just a single button.
-
-There are now additional frame states to style left/right tiled windows
-differently ("tiled_left", "tiled_right", "tiled_left_and_shaded",
-"tiled_right_and_shaded").
-
-New Features in Theme Format Version 3.2
-========================================
-
-A new window type 'attached' is added for modal dialogs which are
-attached to their parent window. (When the attach_modal_dialogs preference
-is turned on.) If no style is defined for the 'attached' window type,
-the 'border' window type will be used instead.

  <shortdesc xml:lang="en">Window and compositing manager based on Clutter</shortdesc>
-  <description>Mutter is a window and compositing manager that displays and
-manages your desktop via OpenGL. Mutter combines a sophisticated display engine
-using the Clutter toolkit with solid window-management logic inherited from the
-Metacity window manager.
-
-While Mutter can be used stand-alone, it is primarily intended to be used as
-the display core of a larger system such as GNOME Shell. For this reason,
-Mutter is very extensible via plugins, which are used both to add fancy visual
-effects and to rework the window management behaviors to meet the needs of the
-environment.</description>

Owen W. Taylor	0a4cfde4e2	MetaWindowActor: Fix crashes when mapping and unmapping windows The assumptions made when getting the size of the window for the paint volume turned out not to be accurate in all cases - get_paint_volume() could be called on windows without computed bounds. https://bugzilla.gnome.org/show_bug.cgi?id=592382	2010-11-13 11:44:47 -05:00
Owen W. Taylor	c853d197e3	Omit shadows for fullscreen and maximized windows Fullscreen and maximized windows never have visible shadows - the only case where we would ever see them is if they bleed onto an adjacent monitor and that looks bad. It's small performance win to avoid computing them, and this also avoids painting the top shadow for all maximized windows in GNOME Shell - since the top panel isn't a X window, it doesn't factor into the computation of what parts of windows are visible and maximized windows are computed as having a top shadow. https://bugzilla.gnome.org/show_bug.cgi?id=592382	2010-11-13 11:44:47 -05:00
Owen W. Taylor	bf7ae3e4d3	Add meta_window_get_maximized() and meta_window_is_fullscreen() These functions duplicate existing properties; they are added for convenience and to avoid the GObject property code on some performance critical painting paths. https://bugzilla.gnome.org/show_bug.cgi?id=592382	2010-11-13 11:44:47 -05:00
Owen W. Taylor	2b21f1d48c	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	2010-11-13 11:44:47 -05:00
Owen W. Taylor	4c91e05b86	Report a correct paint volume for shadowed windows Since we paint shadows directly now rather than using a child actor in the ClutterGroup, we need to implement get_paint_volume() for Clutter 1.5. https://bugzilla.gnome.org/show_bug.cgi?id=592382	2010-11-13 11:44:47 -05:00
Owen W. Taylor	bc91c328f3	Use a template material for shadows To avoid unnecessary shader recompilation, use a root template material for all shadows. https://bugzilla.gnome.org/show_bug.cgi?id=592382	2010-11-13 11:44:46 -05:00
Owen W. Taylor	5bbbac65d6	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	2010-11-13 11:44:46 -05:00
Owen W. Taylor	a0a0fc14d7	Export meta_frame_type_to_string() Frame types will form the bases of shadow classes, which are strings, so export the to-string function so that we can do the conversion uniformly. https://bugzilla.gnome.org/show_bug.cgi?id=592382	2010-11-13 11:44:46 -05:00
Owen W. Taylor	cc9efe1289	Add meta_window_get_frame_type() Add a public function to get the frame type for a window; the code is refactored from existing code in core.c. https://bugzilla.gnome.org/show_bug.cgi?id=592382	2010-11-13 11:44:46 -05:00
Owen W. Taylor	8825ded1ca	Export meta_window_appears_focused() Move meta_window_appears_focused() into the public window.h so we can use it to change the shadow type. https://bugzilla.gnome.org/show_bug.cgi?id=592382	2010-11-13 11:44:46 -05:00
Owen W. Taylor	b823ef0007	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	2010-11-13 11:44:45 -05:00
Owen W. Taylor	a846434bcf	MetaShadowFactory: convert to a GObject https://bugzilla.gnome.org/show_bug.cgi?id=592382	2010-11-13 11:44:45 -05:00
Owen W. Taylor	825fc2c0c8	MetaShadowFactory: Add the ability to top-fade a shadow For attached modal dialogs, we want the shadow to fade out at the top as if the window was glued to the parent at the top. Add a shadow-top-fade property to MetaWindowActor and the corresponding parameter to meta_shadow_factory_get_shadow(). The internal implementation of MetaShadow is adjusted to work in terms of an "inner border" and "outer border" instead of doing the calculations in terms of an aggregate border and the spread of the shadow. The old way of doing things gets clumsy when the top_fade distance is added in as well. https://bugzilla.gnome.org/show_bug.cgi?id=592382	2010-11-13 11:44:45 -05:00
Owen W. Taylor	4fbe547f16	Add frame type for attached modal dialogs Add a new frame type META_FRAME_TYPE_ATTACHED which is used for attached modal dialogs. The theme format version is bumped to 3.2, and attached windows can have borders defined in a metacity-theme-3.xml as: <window version=">= 3.2" type="attached" style_set="[name]"/> If no style is defined for "attached", drawing will fall back to the "border" type. https://bugzilla.gnome.org/show_bug.cgi?id=592382	2010-11-11 18:47:38 -05:00
Owen W. Taylor	fc2ba0afbe	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	2010-11-10 14:42:54 -05:00
