- A double-click in a cell puts the caret where clicked and selects the
word there, as in shapes (it used to put the caret at the end).
- While a cell is edited, a click in the same table moves the caret to
the clicked cell and position; a drag selects text within the cell
and Shift+click extends only within it.
- A click in an already selected table enters the clicked cell at the
click; dragging the table still moves it.
- The release that follows a double-click no longer re-enters the text
at the click, which collapsed the word just selected (shapes too).
Cells are found from the drawn cell rects, so merged cells and rows
that grew to fit their text are hit where they are drawn.
Editing a table cell outlined the cell but drew no caret or selection,
and Up/Down/Home/End fell back to paragraph moves, because the text
layout used for drawing, hit testing and caret movement only existed
for shapes.
text::text_frame now lays out the edited text as it is drawn and gives
the transform to the slide, for shapes and cells alike: a cell's text is
laid out in its rect (merges honoured) with the cell's margins, anchor
and the table style's look, through the renderer's own cell_body and
cell_rects. layout_for and tools::text_pos use it, and the canvas draws
the caret and selection from it. The cell outline follows merged cells.
