Flags to change the way redrawing works, for debugging purposes.
Most useful with 'writedelay' set to some reasonable value.
Supports the following flags:
compositor Indicate what redraws come from the compositor
by briefly flashing the redrawn regions in colors
indicating the redraw type. These are the highlight
groups used (and their default colors):
RedrawDebugNormal gui=reverse normal redraw passed through
RedrawDebugClear guibg=Yellow clear event passed through
RedrawDebugComposed guibg=Green redraw event modified by the
compositor (due to
overlapping grids, etc)
RedrawDebugRecompose guibg=Red redraw generated by the
compositor itself, due to a
grid being moved or deleted.
*'redrawtime'* *'rdt'*
'redrawtime' 'rdt' number (default 2000)
