Summary0001091: AnnotationFiducial: performance issues
Description

1) deleting a hierarchy with 0000020:0000030 fiducials incurs a noticeable delay around 7-8s.

2) flicker of fiducials in 2d-view slice whenever other fiducial is moved across that slice. I have two coplanar fiducials in coronal slice, and move a third back/forth across the axial slice. Each time the third crosses the coronal there is a noticeable flicker of the two fiducials in-plane.

Additional Information

I compiled with the standard instructions on x86, ubuntu 10.04. Qt is binary from the repo:
"""
$ dpkg -L libqt<tab>
libqt3-mt libqt4-designer libqt4-multimedia libqt4-opengl-dev libqt4-scripttools libqt4-sql-sqlite libqt4-webkit libqtcore4

Thanks Daniel and Nicole for this and lots of other recent work. I haven't used annotation in a while, and performance is much improved now.

Deleting a group of fiducials is still really slow, that performace optimisation is still on my to-do list.

Looking again at the Annotations code, the delete is as optimised as I can make it. Suspect that it might be something in the Qt widgets not respecting the batch processing flag on the scene.

All the mrml level optimisations that can be done are done, next level is for the rewrite with a different Qt widget and then different 2d/3d widget implementations.
