    Fix for performance issue when moving shapes.  We don't need to call render except if the geometry and materials change.

    This is more easy to see with shapes like the brush tool.

    resample the brush stroke so we don't have gaps if the path is drawn rapidly,

    and,
    allow to change the stroke color,
    and,
    more efficient stroke rendering by drawing translated radial gradients (instead of creating new gradients for each stroke sample)
