Double click the pointer tool allows easy access to some options.

Note that there is a bit more goodness to this patch as the dialog is
created using the same mechanics as the prefs dialog uses. So you can
in the future cherry pick some options from the prefs dialog into a
new dialog which is tailored to a given situation.
Don't crash when the user clicks on the window manager close window button
Prevent a crash when opening contextual subtables

I don't know why it is crshing now (may be the resources?) as this code have
been like that since the dawn of time.

Double click the pointer tool allows easy access to some options.
Add a utf8_strncpy function
Use a sane default width for matrix edit cells

Instead of defaulting to the whole width of the text, use only the first
40 characters width. Gets rid of insanely wide cells and horizontal
scroll bars in the "simple" contextual substitutions editors with big
lists of glyphs, and even errors like this with very large glyph lists
(e.g. ss01 feature in Amiri):

  Invalid scrollbar bounds min=0 max=-32205, pagesize=33334
Count characters not bytes
Merge remote-tracking branch 'upstream/master'
I moved the pointer_dialog_list lookup table closer to the function which uses it.
