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.

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.
(cherry picked from commit 06a2b4f338)
In GimpDrawTool, update the tool widget on GIMP_TOOL_ACTION_RESUME,
so that it can respond to changes in the display-shell scale/
offset. We'd previously done that for individual tools/widgets,
but let's just do it in one place.
(cherry picked from commit c73710e410)
In GimpDisplayShell, pause and restore the active tool when
rotating the canvas, similarly to scrolling and scaling.
(cherry picked from commit cd5e4e99dd)
There is no non-hackish way of fixing this without adding a new
"use-opacity-paint-mode" property to GimpToolPreset and a new toggle
in GimpToolPresetEditor. Restoring opacity and paint mode can now be
controlled explicitly, and defaults to TRUE.

If we don't do this, the clipboard owner doesn't get unreffed (also the
GtkClipboardClearFunc is not called either, but we don't set any so this
was not a big problem).
The main consequence was that copying was setting the Gimp object as an
owner, which kept a reference and prevent its finalize() method to run,
hence was leaking data (and in particular some GEGL buffers for
clipboard operations, which was how the issue became more visible upon
exit).
