Visualization, OpenGl_AspectMarker - invalid marker size on re-setting aspect without redraw

Description

OpenGl_AspectMarker::SetAspect() resets marker size (myMarkerSize), and then myMarkerSize is set to actual image dimensions within OpenGl_AspectMarker::Resources::BuildSprites().

Within the following scenario myMarkerSize is reset to invalid state:
- Draw marker with Aspect1.
- Set marker Aspect2, but do NOT draw it.
- Draw marker with Aspect1 again.

This is because OpenGl_AspectMarker::Resources::BuildSprites() has an optimization to do nothing when actually loaded marker is the same as requested one - including not updating myMarkerSize.
