Remove the Undo code for deleting a clip and replace it with simpler
parent/child undo relationship.
Move block gathering code to seperate function. It's quite brute
force and might lead to issues further down the line with more
complex composited node setups.
Initial very hacky implementation that checks if the footgae is in
use before deleting it and makes sure all refernences to it are
properly cleaned up.
Also added IsMedia() function to Node to simplify things a bit.
Image streams were initially separated from video streams, but they're now
joined with a parameter defining if they're a still image, image sequence,
or regular video. The image sequence import process has also improved so
that if images from the same sequence are imported too, they'll either be
ignored or the user won't be asked again for those if they should be an
image sequence (fixes#1193). Also shifts decoder "probe" process to return
an item, useful if the decoder returns a non-footage item.
This is the first step in what will eventually be keyframable time
remapping. The speed/duration dialog was a holdover from 0.1 and we can
probably do better here.
Implements a very basic GLSL deinterlace that simply halves the vertical
resolution and then interpolates between the fields. This can be toggled
on or off.
The reasons for being so basic is:
- Speed, very quick code running in OpenGL
- It would seem the highest quality deinterlacers are temporally based
which doesn't make much sense for the viewer, particularly since we can't
double the frame rate since our timecode is fixed to the frames.
Higher quality interlacing/deinterlacing will be present in the actual
renderer.
Implements the following:
- Sequences have pixel aspect ratios that work in tandem with footage PARs
to render footage correctly. Viewer and export also acknowledge PARs
- Sequences can have interlacing settings. This doesn't do anything yet,
eventually the renderer will need to interlace/deinterlace/reinterlace
appropriately in order to conform all the footage to the sequence. Export
acknowledges interlacing, but this only affects metadata, not the image.
