get_visible_nla_strips()

static ListBase get_visible_nla_strips ( NlaTrack *  nlt, View2D *  v2d  )

static

Gets the first and last visible NLA strips on a track. Note that this also includes tracks that might only be visible because of their extendmode.

is_nlastrip_enabled()

static bool is_nlastrip_enabled ( AnimData *  adt, NlaTrack *  nlt, NlaStrip *  strip  )

static

This check only accounts for the track's disabled flag and whether the strip is being tweaked. It does not account for muting or soloing.

This shouldn't happen. If passed NULL, then just treat strip as enabled.

For disabled tracks, only the tweaked strip is enabled.
