In GimpTransformGridTool, extend the functionality of the
"Readjust" button, such that if the transformation is already
adjusted to the view (i.e., when the button is clicked the second
time), readjust the transformation to the item bounds (as when
using the tool "normally"), and vice versa. This allows switching
back and forth between "normal" mode, and "adjusted-to-view" mode.
Additionally, disable readjustment when the current transforamtion
is invalid, and show an error when readjustment results in an
invalid transformation.
In gimp_tool_gui_set_response_sensitive(), silently ignore non-
existent response IDs, instead of emitting a CRITICAL, to match the
behavior of GtkDialog and GimpOverlayDialog. This simplifies code
with optional dialog responses.
This argument should actually say "Do not store premultiplied channel
values", which is what the TIFF spec calls "Unassociated alpha" (vs.
"associated alpha" when values are stored premultiplied by alpha).
Now I can see where the current description is coming from, which is
that any color with alpha 0 (totally masked) ends up as RGBA value (0,
0, 0, 0), in other words, the color information is completely lost. Yet
this label is not very helpful to understand what the checkbox really
does. I decided to not just change it altogether as people would have
gotten used to this for years, but at least adding completary
information in API and tooltip in GUI.

cherry-picking over-complicated for just one line)
When the "wrap" property of a GimpSpinButton is TRUE, wrap-around
out-of-range values entered through the spin-button's text entry,
instead of clamping them. Since we're using GimpSpinButton
everywhere since last commit, this applies to all our angle-entry
spin buttons (including spin scales).
Not sure what this @image_types parameter of gimp_install_procedure() is
used for. Exporting was working find with INDEXEDA image even when not
advertized by this function. Let's update this anyway.

In the unified-transform, scale, and perspective tools, take the
maximal transform-grid handle size into account when readjusting
the transform, so that the handles themselves are fully within view
under arbitrary rotation, rather than just the corners.
Since the color being currently edited is the selected one, it makes
sense that the fg/bg color should be updated appropriately.

In GimpTransformGridTool, reset both transform directions in
response to the "Reset" button, so that the overall transformation
is restored to the identity. Previously, we would only reset the
active transform direction (possibly compensating in the opposite
direction, if both directions are linked). This was intentional,
but it's probably a bit too confusing, especially in conjunction
with the newly added "Readjust" button. Let's just go back to
resetting everything.
