No balloon help if continuous redraw

[goddard@…]

The following bug report has been submitted:
Platform:        Darwin-18.6.0-x86_64-i386-64bit
ChimeraX Version: 0.91 (2019-06-27)
Description
Atom name balloons don't appear if graphics is continuously being drawn such as when "graphics framerate true" is used.  This case isn't very troublesome since that command is rarely used.  But ISOLDE with a simulation running could potentially also block balloons.  In practice I have not seen this problem in ISOLDE, probably because it does not draw every frame.

Currently the code only considers showing a balloon on frames when no redrawing of the scene is done.

This behavior is by design. To provide best responsiveness when graphics is being redrawn, balloons are not shown. Cases where graphics are continuously being redrawn and balloons would be useful are rare.

If balloons are only shown when mouse was moving and then stops and no buttons are held down, seems like it should not impair responsiveness. Might try that. Possibly the current behavior was so that mouse button down drag does not cause balloons.

Fixed.

Allowed mouse hover balloons after mouse moves then stops when no mouse buttons down.
