Check at runtime for the operation availability and set the "Show Image
Graph" action active depending on this check.
This goes with discussions to make this operation optional with a
runtime check for the tool `dot`.

Was caused by widget tool fixed_center_x and fixed_center_y coordinates set to
coordinates of mouse click instead of rectangle center after converting channel
selection bbox to rectangle.
Now rectangle fixed_center_x and fixed_center_y coordinates are always updated
when tool widget x1, x2, y1, or y2 coordinates are updated.

The Lua API is undergoing changes in darktable master. I've fixed the lua-scripts repository as I've made
changes, but I forgot about the collateral damage.
Attached is a fixed version of file-darktable-export-on-exit.lua which should be good for darktable 3.6 and
beyond.
Fixes#6421

This commit also makes snap to grid and snap to vectors work off-canvas.
Since we now have off-canvas viewing, it just makes sense that snapping
would work there too.
Note that I disable snap to grid when "Show All" is OFF. I am actually
unsure this is right (as "Show All" is a view action, and we usually
don't change behavior based on view actions; for instance snap to guides
are not disabled if guides are hidden). Yet I noticed we do this in
various other features when off-canvas. We kind of use this view flag as
a switch for features working off-canvas (for instance, color picking
works off-canvas only when "Show All" is ON). So let's keep the same
logics for now at least.
Snap to guide or snap to vectors will always work though, because guides
and vectors are always visible off-canvas (even when "Show All" is OFF).
They always have been (visible, not snappable off-canvas; now they are
both).

If the interp file contains CRLF, the \r is read as part of the
executable file name, and gimp searches for python3.exe\r.

This commit fixes the issue when requested page width/height was
not honored because DPI resolution value was constrained to whole
integer numbers only.
XMP metadata saved by GIMP 2.8.x or earlier can have duplicate tags
making the XMP data invalid. There's not much we can do without a
whole lot of processing and complicated code and even then no
guarantee we would catch everything.
Instead let's just try to improve the message to the user so they
will be more likely to understand what's going on.

Although I haven't been able to reproduce it, it is apparently
possible to get a Stack Overflow when loading xcf files with
presumably very large dimensions on Windows. From what
I'm reading Windows normally has a smaller stack size than
Linux, probably why it hasn't surfaced there.
Instead of allocating on the stack let's do a g_malloc0
combined with g_free.
