Subject: [PATCH] Type tool: a drag across text that isn't being edited selects
 it

A press only started a selection inside the text being edited; on other
type it waited for the release, which placed the caret at the press and
ignored the drag, so the first drag across a word never selected it.
A press on type now starts editing it there (the same code a click used
on release), so the drag selects at once; a plain click still just
places the caret.

Fixes #245.
