Review request for Kdenlive.


Repository: kdenlive


Description
-------

This simply exposes access to the LUT effect of libavfilter. This is for initial review only and probably shouldn't be merged right away for several reasons:
 * There is a bug in melt regarding this effect that needs to be fixed first (affects users with european locale). See https://github.com/mltframework/mlt/issues/130
 * The UI is not optimally pretty because I cannot get the URL Picker to behave nicely (it takes all space possible instead of justifying to the left as a text field for example)
 * It is proably time to define a standard way to standardize the extension filters of the urlpicker. Currently the xml object corresponding to an url has no way to define this (and I had to temporarily disable filtering altogether in the code)
 * I've set a "full" description of the filter but I don't see where it is showing up in the current UI.
