   Yes. The original anticipated use was for small numbers of errors
being shown with indicators. Therefore the feature was implemented in
a simple way without much thought about performance. The plain line
indicators will draw fast but, for example, INDIC_SQUIGGLE will be
slow as it is drawing a long sequence of short lines.

   If performance is an issue then you could convert this to using a
long cached pixmap as the source of a copy onto the window.
