4c69dabb6e Don't return GDK_GRAB_SUCCESS on failure
That seems ... counterproductive.

038aac6275 gdk: Add support for OpenGL
This adds the new type GdkGLContext that wraps an OpenGL context for a
particular native window. It also adds support for the gdk paint
machinery to use OpenGL to draw everything. As soon as anyone creates
a GL context for a native window we create a "paint context" for that
GdkWindow and switch to using GL for painting it.

This commit contains only an implementation for X11 (using GLX).

The way painting works is that all client gl contexts draw into
offscreen buffers rather than directly to the back buffer, and the
way something gets onto the window is by using gdk_cairo_draw_from_gl()
to draw part of that buffer onto the draw cairo context.

As a fallback (if we're doing redirected drawing or some effect like a
cairo_push_group()) we read back the gl buffer into memory and composite
using cairo. This means that GL rendering works in all cases, including
rendering to a PDF. However, this is not particularly fast.

In the *typical* case, where we're drawing directly to the window in
the regular paint loop we hit the fast path. The fast path uses opengl
to draw the buffer to the window back buffer, either by blitting or
texturing. Then we track the region that was drawn, and when the draw
ends we paint the normal cairo surface to the window (using
texture-from-pixmap in the X11 case, or texture from cairo image
otherwise) in the regions where there is no gl painted.

There are some complexities wrt layering of gl and cairo areas though:
* We track via gdk_window_mark_paint_from_clip() whenever gtk is
  painting over a region we previously rendered with opengl
  (flushed_region). This area (needs_blend_region) is blended
  rather than copied at the end of the frame.
* If we're drawing a gl texture with alpha we first copy the current
  cairo_surface inside the target region to the back buffer before
  we blend over it.

These two operations allow us full stacking of transparent gl and cairo
regions.

7f35708cee gdk: Add touch event types and mask
This commit introduces GDK_TOUCH_BEGIN/UPDATE/END/CANCEL
and a separate GdkEventTouch struct that they use. This
is closer to the touch event API of other platforms and
matches the xi2 events closely, too.

9c79f9f868 Turn the private #define for the group-shifting modifier into API
Add GDK_MODIFIER_INTENT_SHIFT_GROUP to enum GdkModifierIntent
and handle it in gdk_keymap_get_modifier_mask(). Add an X11
impl of the method and return keymap_x11->group_switch_mask.
Return 0 from the default impl because we don't know.

4a7a67339a Bug 659602 - Provide an abstraction for the platform's use of modifier keys
Add enum GdkModifierIntent which identifies use cases for modifier masks
and GdkKeyMap::get_modifier_mask(). Add a default implementation which returns
what is currently hardcoded all over GTK+, and an implementation in the
quartz backend. Also add gtk_widget_get_modifier_mask() which simplifies
things by doing widget->display->keymap->get_modifier_mask().

7bc2f539d0 Explicitly declare internal reserved bits in GdkModifierType
XKB and GDK both add "internal" bits to GdkModifierType.  In C,
this typically doesn't cause problems as bitfields are just integers,
and there's no validation.  However for bindings, it's normal to
convert enumerations to "native" enumeration types, which don't
support unknown bits.  See bug 597292.

ec9c97752d Work toward turning GdkDisplayManager into a backend singleton
This commit hides the GdkDisplayManager instance and class structs,
adds vfuncs for listing displays, opening displays, and getting and
setting the default display. The X11 backend has a derived
GdkDisplayManagerX11.

The gdk_display_manager_get() function is responsible for deciding on
which of the compiled in backends to use. Currently, it consults the
GDK_BACKEND environment variable and falls back to x11.

06f75b3727 Make GdkAppLaunchContext display-dependent
Add a GdkDisplay::get_app_launch_context vfunc, and a
gdk_display_get_app_launch_context that for X11 returns a subclass.
For win32 and quartz, the implementations were trivial, so we
just return a new GdkAppLaunchContext without subclassing. Since
the type of the context now depends on the display,
gdk_app_launch_context_set_display is deprecated.

5a5f8081f0 Add GdkRGBA struct to supersede GdkColor
GdkRGBA is a boxed struct similar to GdkColor, with the difference
that it stores alpha information as well, and colors are stored in
[0..1] doubles, in the cairo spirit.

gdk_cairo_set_source_rgba() has been also added to allow easier handling
of this new type.

3963d5aa76 Remove variables from the platform-independent GDK API
gdk_threads_mutex, gdk_threads_lock and gdk_threads_unlock are removed
from public API. gdk_threads_mutex was deprecated already. Instead of
using gdk_threads_lock and _unlock one was presumably supposed to use
the GDK_THREADS_ENTER and _LEAVE macros, which now simply call the
corresponding gdk_threads_enter() and _leave() functions.

Remove he dllimport/dllexport ugliness for GDK for Windows.

There is still a gdk_display variable being exported by the X11
backend.

was opaque anyway so it doesn't matter and the rectangle types are
