Documentation

When non-nil, redraw based on face filters.

When this variable is non-nil, force a potentially expensive redraw when a window parameter named in a :window expression for ':filtered' changes. This redraw is necessary for correctness; this variable is an escape hatch to recover performance in the case that our assumption that these parameter changes are rare does not hold.

You can also inhibit the automatic redraw for a specific window parameter by setting the `:filtered` symbol property of the parameter name to ignore'.
