Open a PDF in LOK mode, insert a signature line, try to drag the
selected signature widget/shape, nothing happens.
Given that the inserted shape has a default position at page center, you
typically want to adjust that default position, but that requires adding
a few exceptions, since PDFs are normally read-only. Desktop Impress
gets around this since commit 5d29618307
(sd signature line: allow move / resize of shape before signing,
2020-06-26), but LOK clients want to rather dispatch an UNO command
(instead of handling this in the mouse event handler), so this requires
additional work.
A first problem is in isCommandAllowed() in desktop/ that explicitly
rejects the UNO command for read-only documents: allow this when a
signature widget is selected. A second problem is in
SdrEditView::SetGeoAttrToMarked(), check for the signature widget there
as well.
Given that the implementation of .uno:TransformDialog already has a set
of flags to prevent doing anything for read-only documents, it looks
safe to allow the execution of the command itself. The size of the
widget should be also possible to modify, that's not yet done here.
