Framework:
* Trigger a `property-changed` event on
`mlt_properties_pass_list`.
* Fixed using a video transition with a video clip on an audio
track.
* Reduce the amount of service caching to 2X #tracks to reduce
memory usage.
Modules:
* Added the `pillar_echo` filter to the plus module.
* Added a `qtcrop` filter to the qt module.
* Added `html`, `resource`, `overflow-y`, and `_hide`
properties to the `qtext` filter for rich text.

with non-integer frame rates.
* Fixed a regression in version 6.22 with multiple affine
filters at the same time.
* Fixed possible abort or deadlock on recursive pthread
mutexes in `avformat` producer.
* Fixed a crash in `crop` filter with large `center_bias`
value when `use_profile` is 1.
* Fixed a white video frame appearing on threaded rendering in
`freeze` filter.
* Fixed MLT XML DRD to permit empty playlists, which may occur
on empty tracks in a multitrack.
* Fixed initializing QApplication in the `qimage` producer.
* Fixed interpolation when scaling with the `affine` rect and
geomety properties.
* Fixed high memory usage with high factors of pitch shifting
in the `rbpitch` filter.
* Fixed a crash on files with more than 32 streams in the
`avformat` producer.
