When a fill zone was a bit too segmented, you'd want to just stroke
across it. But it was leaving some pieces uncolored, even though the
pointer dragged through it! The exact motion mode allows more events.

Note: I don't set it in the similar color filling (where it could have
been useful too) mostly because it is harder to remove events then (even
if a point was already filled, it could still serve as a seed for more
filling if threshold > 0), thus implied too much processing. Anyway in
all my tests, it was more a problem for line art filling anyway.

In GimpToolRectangle, fix the type of the cornder_radius field, so
that non-integer radii are properly displayed.

In GimpRectangleSelectOptions and GimpToolRectangle, increase the
maximal corner radius.

Add a Sample Merged option to smudge, a lot like for heal, just needed
tweaking in more places.

In GimpMaskUndo, align the copied region to the source buffer's
tile grid, so that all copied tiles are COWed.

We were doing it all the wrong way, fixing one combo box object at a
time. So this commit basically reverses commits 68a33ab5, 6dfca83c
and a9a979b2 and instead runs the same code in the class code. This
way, all objects based on these base classes will have the fix from
scratch.
These improved various other drop-down lists (I found some of them, and
probably not all) as I fixed all GIMP custom widgets based on
GtkComboBox.

Note that it has to be run after filling the list apparently (I had the
problem especially with GimpIntComboBox if running in the _init() code,
then the list widget showed wrong).

(cherry picked from commit 1d984542)

Just another instance of the GtkCombo issue, same as #2642.

gimp_heal_motion(): when sample merged is active, simply initialize
the paint buffer from the projection instead of the drawable.

When clearing a channel, do nothing if the channel is already
empty; otherwise, align the cleared rectangle to the channel
buffer's tile grid, so that all affected tiles are dropped, rather
than zeroed.  Furthermore, only update the affected region of the
channel.

In GimpDrawableFilter, when operating on a layer, update the filter
when the layer's lock-alpha flag changes.

In commit c71b4916, I forgot to disconnect signals on the bucket fill
options at finalization, leading the software to crash on an
non-existing tool.

(cherry picked from commit 0a952a34)

After discussion with Sébastien Fourey and David Tschumperlé, it was
decided that a better fix for the edge case raised in #2785 was to add a
keypoint anyway, even if the point and none of its neigbours have a
positive smoothed curvature, yet they have a positive raw curvature. In
such case, we use the local maximum raw curvature instead of the local
maximum smoothed curvature.

Additionally to sample merge and active layer, now we can only use the
layer above or below the active layer as line art source.

The line art fill is meant to work on drawing lines. Though sample merge
still is ok in many cases, the more you fill with colors, the more the
line art computation becomes unecessarily complex. Also when you use a
lot of layers with some of them already filled with colors, it makes it
impossible to colorize some line art zones with the tool. Moreover you
just don't want to have to hide every layers out there to colorize one
layer (especially background layers and such as you may want to see the
result with your background).
Thus we want to be able to set the source as a unique layer, while it
not being necessarily the active one (because you want lines and colors
on different layers). In this case, I am assuming that the color and the
line layers are next to each other (most common organization).

In GimpTileBackendPlugin, change the default tile multiplier,
specifying the ratio between the backend tile-size, and GIMP's
tile-size, from 2 to 1.  Since we're reading/writing each GIMP tile
using a separate command anyway, using a large multiplier doesn't
provide any benefits, while it does have drawbacks.  In particular,
it reduces the chance that a write operation will affect an entire
tile, which allows us to avoid reading the tile data from GIMP.

(cherry picked from commit a5e2945b)

Add an internal _gimp_tile_ref_noinit() function, which increases
the ref-count of a tile *without* initializing its data (in
particular, without reading its data from GIMP, or zeroing it.)
Use this function, instead of gimp_tile_ref(), when storing a tile
in GimpTileBackendPlugin, to avoid unnecessarily reading the tile
data from GIMP.
