Hi!

Nice to see that work when coming back from holiday!

Regarding your MLT changes, I have a few remarks:

1) I had to link against QtXml to make it compile (added it in 
src/qimage/configure everywhere there is a  QtGui ).

2) When trying to produce an xml output from a kdenlivetitle producer, I get a 
wrong resource, try:

melt title.kdenlivetitle -consumer xml

This is because the "resource" property is not set in the 
"producer_kdenlivetitle_init" method (see producer_qimage.c to see how it is 
done here). Should be something like adding the following 2 lines around line 
111 in producer_kdenlivetitle.c

mlt_properties properties = MLT_PRODUCER_PROPERTIES( this );
mlt_properties_set( properties, "resource", arg );


3) When I try to play a .kdenlivetitle file from melt, I get the following 
warning:
WARNING: QApplication was not created in the main() thread.

Not sure if it can be fixed and how dangerous it is...

About the changes to Kdenlive, it's a good start. We will probably need to find 
a better way to set the start/end viewport since it is currently not very 
great. Also, the x / y position for start / end viewport currently have a max 
limit of 1000 which is far from enough, but that's just a detail.
