Partially revert commit c73710e410,
avoiding updating tool widgets unconditionally on tool resume in
GimpDrawTool -- it's too expensive in general.
Instead, handle display-shell changes in GimpToolWidget, by adding
GimpToolWidget::update_on_{scale,scroll,rotate} flags, which
subclasses can use to request an update on any of these events.
Set the flags as necessary for the affected widgets.

In GimpImageProxy, implement GimpColorManaged by forwarding the
functions to the underlying GimpImage, and forwarding the signals
in the other direction. This fixes color-managed view in the
Navigation dockable.

When converting an image to indexed mode, zero-out transparent
pixels instead of leaving junk in their indices, which might well
be out of range of the palette.

Wherever we store arbitrary-format colors in an opaque buffer, use
double for the buffer, instead of char, so that it has a strict-
enough alignment to handle all our used pixel formats.

This fixes:
> GEGL-WARNING: (../../src/gegl/gegl/buffer/gegl-tile.c:127):gegl_tile_dup: runtime check failed: (! src->damage)
Which happened when a GEGL operation was running and you canceled it in
the middle, say with the ESC key (easy to reproduce with long operations
such as "Color to Gray"). In such case, obviously don't try to copy the
unfinished operation result into the dest buffer.

When using "show all" by default, gimp_display_flush() can be
called during GimpDisplayShell construction, before the newly-
constructed shell is assigned to the display. Use an ugly hack to
just ignore the flush when this happens.

gegl:focus-blur blurs the image around a focal point. It can be
used to create fake depth-of-field effects.
Add a prop-gui constructor which uses a FOCUS controller to control
the focus geometry.
(cherry picked from commit 60d4d25b93)
Add a new GimpToolFocus tool widget, which defines a focus region,
consisting of an inner limit, an outer limit, and a transition
midpoint between them. The widget allows controlling the limits
and the midpoint, and moving, scaling, and rotating the region.

... which constrains an angle to discrete increments in screen
space, similarly to gimp_display_shell_constrain_line().

Add a new GimpCanvasLimit canvas item, which draws an area limit
for different shapes. It will be used by the following commits to
implement GimpToolFocus.
