[linux-audio-dev] ardour 0.9beta19 released

(not the "feature complete" release I was planning, but the list of changes is enough to warrant a new beta number) Changes since 0.9beta18.4: * optimization flags patch from rob holland * drag-n-drop onto the editor track area where there is no track creates an appropriate track (or multiple, if appropriate) * URL-decode drag-n-dropped filenames * numlock can no longer mess up region dragging - if numlock generates whatever "Meta" is supposed to be then Ardour changes its notion of what Meta is. - if you see a warning about this in the terminal at startup, you should fix your keyboard map using xmodmap or equivalent * remove debugging output from process() tree * removed VST audiomaster callback debugging output * UI for VST plugins now offers presets * VST plugins now save and restore their state - "chunk"-using plugins are not yet supported * initial tempo and meter markers cannot be moved, even after editing * when cleaning up, prompt user about each unused playlist (options are delete, keep, cancel cleanup) * never decrease the number of panning buffers * Can't create a new session on top of an old one anymore. It didn't overwrite the old session, but you would get 2 master tracks and whatever was in the template, if any. * freezing tracks - implementation of freeze completely redone - unfreeze now works across invocations of ardour, so you can freeze, exit, restart and unfreeze. - freeze hides any insert editors, makes rec-enable and redirect display widgets insensitive and locks the new region. - freeze can be used over and over again * reworked relationship between bounce + freeze * removed "Loop Region", renamed "Loop Selected Region" as "Loop Region" because of click-selects selection model * finally made solo button in mixer strip have the same font size as other buttons * removed edit history button and associated code from editor track * removed "automation style" buttons since they did nothing * more automation line + point patches from gerard * fix a couple of valgrind complaints * region trimming now obeys ignore-snap modifier * search unused playlists in Session::playlist_by_name() * added 2-phase unserialization mechanism (Session::StateReady signal) * empty playlists assigned to correct diskstream at startup * removed some debug printfs and some dead code * make Shift_R work like Shift_L * fix crashing bug with zero-length fade ins * internationalize all editor operation strings * transport control is insensitive when there is no session * fix problems with "region->fill track" where region is at or beyond current session end * new mixer strips use the current default width setting * always save to snapshot * snapshotting changes the current snapshot to whatever was saved * delete click_io object at session close, thus allowing new sessions to load correctly * fix problem with code ordering in normalize-region operation (undo after normalize-then-cut will now do the right thing) * force selection.clear() in file selection browsers when widget selections are cleared * committed patches so that ardour now compiles with gcc-3.4. There were several patches from multiple people. So please let me know if I missed one. * patch from nick_m that fixes a problem with the editor-mixer button.
