* 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.
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.
And turn it from a boolean to an enum. It can be set to:
* `none` - disables the indicator
* `static` - always rendered near the top of the window
* `moving` - position reflects the scrollback position
search_update_selection() was changed in 1.4.x to *first* update the
selection, *then* move the viewport.
This leads to a crash if the new match (selection) is outside the
current viewport; the selection code assumes the updated selection
endpoint is in the visible viewport.
Changing back to *first* move the viewport, *then* update the
selection solves this.
* Don't move the viewport if the new match is already fully visible
* When we do have to move the viewport, position it such that the new
match ends up roughly in the middle.
Previously, our secondary DA response indicated a) VT420, b) an XTerm
version number.
Now, we indicate VT220 (which corresponds to the primary DA response),
and we report foot's version number as MMmmpp. I.e major, minor and
patch versions, using two digits.
E.g. 1.4.2 is encoded as 010402
When copying the image data for the left and right parts of the
splitted images, use the sixel's height, not the cell height.
This fixes a crash when the sixel didn't cover the entire cell height.
