When writing Kdenlive, LinearTimewarp effects will be included. If a clip has multiple, their effects are concatenated into a resulting speed.

… a .prproj using my otio-premiereproject adapter to .kdenlive and then opening in Kdenlive.
…miereproject on read, if anywhere). Reverted offsetting all time to 0 (I think Kdenlive either does or should handle that).
…w matches algorithm from mlt source code (haven't properly looked into it, but it's possible Python's str(datetime.timedelta(...)) is broken). Correctly uses end_time_inclusive when writing time ranges - and equivalent when reading. Converts file:/// uris to file path on the way out.
… testing. An export from Premiere from a genuine thing I was editing. In the process of writing the test discovered another bug in the from Kdenlive time string function. Written it to accurately reverse the process in the clock function; written having referred to the source code of mlt. That source code is technically flawed. I believe it isn't written with non-integer frame rates in mind.
