[PiTiVi] Progress Update

[Brandon Lewis <brandon_lewis berkeley edu>]

Refreshing everyone's memory, PiTiVi is an open source, non-linear video 
editor. I'm working on a simplified interface which replicates iMovies's 
 functionality. PiTIVi is organized around the concept of a "timeline" 
which contains multiple "sources" each with an associated start point 
and duration.

Last week I had wanted to work on the editing widget, but I ran into 
this bug which caused PiTiVi to crash when dragging a source ot the 
timeline for the first time. The problem was related to an instructional 
message displayed in the timeline initially. My first attempt at a 
solution completely broke the code by rendering the timeline invisible. 
I lost several days on this effort. I lost a couple of days last week 
due to traveling from Burlingame, CA to San Diego, CA, a round trip 
distance of rougly 1000 miles.  I took one day to rest after returning, 
and then lost another day due to a migraine headache.

The last few days have been relatively productive. I spent some time 
cleaning up the editing widget. Chief among my concerns was making sure 
that the thumbnails in the SimpleEditingWidget were updated properly 
when the source's start and stop times were set. I also spent a good 
amount of time making the editing slider functional; however, I think I 
will probably re-implement most of this code later, when I make a 
separate "PipelineSlider" class.
