Tracker: Improve pose loading speed, add comments
If a new pose is going to be placed below the current view bounds, we
definitely do not need to do any drawing. If it is above or inside the view
bounds we do this special drawing method.
Overall this method of doing updates is complicated and hard to adjust without
introducing drawing artifacts. As noted in the TODO, this should be rethought
from scratch.
But for now in one case of over 8000 files in a single directory this improved
the loading speed from about 8 or 9 seconds to 1. Queries results also load
much faster. I am testing in a VM with a single CPU on a host with an SSD, so
others may see better performance with more CPUs, or less with a spinning hard
drive.
But at least now the drawing won't be the bottleneck.
Should finally fully fix #3011, or at least good enough for close.
