Previously, we calculated the monitors horizontal and vertical PPI
values.
For font sizing, we used the vertical PPI value. It seems however,
that using the diagonal PPI value, i.e. diagonal_px / diagonal_inch,
gives more consistent results.
This is still a PPI value, but since it is intended to be used as a
FontConfig DPI value, name it 'dpi'.
* Fix col/row calculation in pointer-enter event; we did not take the
margins into account.
* seat->mouse.col,row are now set to -1 if the cursor is inside the
margins. That is, col/row are only ever valid when the mouse is
actually over the grid, and not in the margins.
* Use regular 'left-ptr' mouse cursor when mouse is inside the
margins, to not make the user think he/she can start a selection.
Besides making things clearer, this also fixes a crash that occurred
if you started a selection in e.g. the right margin.
We only support escaping quotes inside a quote, and only of the same
type as the enclosing quote.
I.e.
"double quote \"escaped double quote\""
But not
"double quote \'invalid escaped single quote\'"

When scrollback indicator has been enabled, and the viewport isn't at
the bottom, we now render a *static* indicator with the position in
percent.
We use the color scheme's blue color as background, and it's white
color as foreground. This is subject to change... Should maybe be
configurable as well.
The Wayland surface + sub-surface are instantiated on-demand, and
automatically destroyed when no longer used.
