code changes:
bbt_ variables don't need to be global to editor; we only use these in compute_bbt_ruler_scale now anyway
drive the ruler with the same coarse-ified bbt_ruler_scale that we calculate for the snap grid

git history begins in 2005. So (C) from 1998..2005 is lost. Also some
(C) assignment of commits where the committer didn't use --author.
This fixes an issue with the session being marked as dirty without
any actual change. Also this method indirectly called during session-load
when the UI state is restored, a potential race with "Session::Loading"
being unset.
- remove trailing whitespace
- remove space after opening brackets and before closing brackets
- add space around operators
- do not use '//' for multi-line comments, do not use "//" on line-start
to comment-out code breaking indenting (-Wmisleading-indent)
- do add a single space after comment-start /*{SPACE}... or //{SPACE}...
- reserve duplicate whitespace " " for alignment, remove other duplicate
whitespace
- use established "TODO" and "XXX" (highlighted keywords)
- remove equal-sign series "====" (those indicate merge conflicts)
Separate Snap from Grid. Lots of naming changes.
Multiple simultaneous snap options allowed. Grid is one of the possible Snap options.
Grid uses the same data as the rulers. Replace complicated tempo_lines with simple grid_lines.
The Grid is zoom-scale-sensitive along with the rulers. If you are zoomed out, grid becomes coarser.
Generated by tools/f2s. Some hand-editing will be required in a few places to fix up comments related to timecode
and video in order to keep the legible
This fixes a bug for me:
Measure lines appear & disappear during playback, at certain zoom scales.
I think this is because the unecessary offset was causing beat_density to vary unnecessarily while rolling.
- when the timeline displays many bars, zoom/autoscroll
speed is improved by calculating the bbt ruler scale first
then requesting a suitably scaled grid.
- audio-locked midi regions can be start-trimmed properly
when close to 1|1|0
- a midi region placed before the first meter
will continue the tempo curve and first meter.
Only a couple of callers require change, as bbt_at_beat() already
deals with this.
Replaces the list of points in TempoMap with TempoSection functions, which
compute tempo-at or tick-at time relative to tempo section start.
TempoMap consults them additively to determine things like bbt_time(),
frame_time() get_grid() etc.
This has a marked effect on scrolling speed along with the code simplification
in the places it has been attempted.
Several things are broken here.
Currently every ramp except the last one is an exponential ramp. this may
be simple to fix :).
Mouse-over midi grid doesn't match mouse click grid. should also be simple.
Many things seem to work, but their accuracy should be in question until
each area has been addressed.
Change ruler context actions from "Make Loop range" to "New Loop range"
change ruler context actions from "Make Punch range" to "New Loop range"
This to make it consistent with other ruler context actions eg. "New....."
Remove the is_xrun parameter from Editor::mouse_add_new_marker(), and just
create the marker directly in ARDOUR_UI::create_xrun_marker(), so that xrun
markers don't become automatically selected when they appear.
Remove Canvas::Layout, use Canvas::Container for the same purpose, move child-rendering into Item::render_children() so that it
could theoretically be used by any derived type.
When zoomed in to the millisecond level, the framerate was being divided
by 1000 as an integer to generate a ruler tick interval, which doesn't
work so well at things like 44100 or 88200. Instead, just count this
value in milliseconds, dividing by 1000 when we are done.
This was purely a display issue - the grid was in the correct place.
timeline thumbnail display, moving (drag/drop) and zoom works.
There still some crashes e.g. resizing the height of the timeline
and with off-screen image buffering when zooming in.
Likely due to concurrency issues:
VideoImageFrame::exposeimg() and direct access of the pixbuf:
"Assertion `!_bounding_box_dirty' failed." in canvas/item.cc:191
more work is needed..
