Characters that needed to be inserted in text mode in mathed were not
correctly inserted. Here we do two fixes:
1/ in niceInsert(), do not replace the contents of the active insets
first cell with selection, insert selection instead. This wa sthe
cause of the bug: an empty selection replaced the contents that was
already in the cell.
2/ do not use niceInsert() anyway, insert() is perfect for what we
want to do.
Fixes bug #11527.
The idea is simple: we insert a pre-formatted table (with a given border
style currently, but other attributes are possible as well) via file-insert
and scale it then to the requested size.
We need three sizes (1x1, 1x2 and 1x3) to generate all sizes properly (due
to border specifications).
Currently, these styles can only be accessed via lfun tabular-style-insert
and the Tabular Create dialog.
My plan is to add a buffer param to set a default style (#9901) which then
also is respected by the toolbar button and probably a layout tag to let
classes specify a default style (#8360).
Attempt to save the template in the appropriate language subfolder of
the user template directory (and propose to create it if it doesn't exist
yet).
That way, user-generated templates (1.) get the correct language attribution
in the lyxfiles dialog and (2.) users can easily generate different
language versions of a template.
Several changes are needed to get things right:
* nested supersripts only work with inheritFonts=true.
* to get caret position right, it is necessary to remember the outside
font of the inset before computing metrics.
* to get the size right at insertion time, it is necessary to trigger
a metrics computation just after inset insertion.
While math style (scriptstyle,...) is not really something that can be
set, it is useful for text subscripts and superscripts and therefore
it makes sense to handle it in some places.
With this change, style is still not a first class feature, but good
enough for now. In particular, it is taken into account in update().
