Allows using up to date simde and newer compilers for small performance
improvements. Ubuntu 18 and 20 are EOL and Ubuntu 22 was released over four
years ago.
This will also hopefully allow us to build slang for the upcoming
transition to slang based shaders.
When focus_follows_mouse is enabled, returning to a desktop/space fired an
enter event that switched the active window to whichever one was under the
cursor, even though the mouse had not crossed a window boundary.
Distinguish genuine mouse motion into a window from a window reappearing
under a stationary cursor by checking, in cursor_enter_callback, whether the
cursor position actually changed. focus_follows_mouse now switches focus only
when the cursor moved, so motion into a window still switches focus while a
stationary reappearance does not.
Adds an `equalize` layout action that redistributes split sizes so each
window receives a proportional share of space along each axis.
Also adds an `equalize_on_close` layout option that automatically
equalizes splits whenever a window is closed, keeping the remaining
windows balanced without requiring an explicit key binding.
These two features compose well. For example, to keep splits balanced
at all times - equalizing on every open and close:
enabled_layouts splits:equalize_on_close=true
map ctrl+' combine : launch --location=hsplit --cwd=current : layout_action equalize
map ctrl+/ combine : launch --location=vsplit --cwd=current : layout_action equalize
A standalone key binding for manual rebalancing is also supported:
map ctrl+shift+e layout_action equalize
