tk: Resize the canvas, not the figure.

QuLogic · QuLogic · commit 1b82a9627dcd · 2020-03-27T02:30:56.000-04:00
Resizing the figure directly does not account for the toolbar, so figures are actually a little shorter than they should be. The recent change to `Text.get_window_extent` some how causes this to actually get reflected in the Matplotlib figure size, which cycles back to Tk and shrinks the window. However, this can be triggered by other calls to `Figure.set_size_inches` as noted in the fixed issues. Fixes #10083. Fixes #10566. Fixes #16926.
