@item corner_rounding
Render frames with rounded corners. The value, given as a float ranging from
@code{0.0} to @code{1.0}, indicates the relative degree of rounding, from fully
square to fully circular. In other words, it gives the radius divided by half
the smaller side length. Defaults to @code{0.0}.
