This commit adds a new RightMainVerticalStack layout, adapting code from
the similarly named LeftWM layout.
It turns out that the horizontal axis flip on the VerticalStack does not
play well with resize offsets.
It was ultimately easier to implement this layout and the logic for
resizing both VerticalStack and RightMainVerticalStack independently
than to make resize offsets and horizontal axis flips work together.
I still have no idea why resize offsets and horizontal axis flips aren't
working properly together.
Horizontal axis flips have been disabled for both the VerticalStack and
RightMainVerticalStack layouts.
re #789
This commit introduces a number of refactors to layouts in general in
order to enable navigation across custom layouts and integrate both
default and custom layouts cleanly into komorebi and komorebic.
Layout has been renamed to DefaultLayout, and Layout is now an enum with
the variants Default and Custom, both of which implement the new traits
Arrangement (for layout calculation) and Direction (for operation
destination calculation).
CustomLayout has been simplified to wrap Vec<Column> and no longer
requires the primary column index to be explicitly defined as this can
be looked up at runtime for any valid CustomLayout.
Given the focus on ultrawide layouts for this feature, I have disabled
(and have not yet written the logic for) vertical column splits in
custom layouts.
Since CustomLayouts will be loaded from a file path, a bunch of
clap-related code generation stuff has been removed from the related
enums and structs.
Layout flipping has not yet been worked on for custom layouts.
When switching between Default and Custom layout variants, the primary
column index and the 0 element are swapped to ensure that the same
window container is always at the focal point of every layout.
Resizing/dragging to resize is in a bit of weird spot at the moment
because the logic is only implemented for DefaultLayout::BSP right now
and nothing else. I think eventually this will need to be extracted to a
Resize trait and implemented on everything.
