Create WaveTrackCache as a utility class but don't use it anywhere yet.
The possible minor performance problem with effects is fixed by changes
in WaveTrack::GetBestBlockSize().
As usual, I started out intending to do as little as possible
to this to get it working and wound up going overboard.
However, I believe it does allow easy management of the effects
and this will provide a basis for the full blown plugin manager
dialog.
It started out as just the fix for #884, but it went
a bit further. Steve had the idea for the zoom and
pan addition, so I added it while I was working on
On a reset preferences, this adds the default built in effects only. The effects menu now has a 'More...' as its last item, and the list of plugins is invoked there. We can add from that list to the menus from that.
I've added code that now treats sample editing as another kind of mouse capturing activity (IsAdjustingSample). We will now not undo or redo whilst mouse is captured. Does not depend on what key binding is used for redo/undo.
This captures crashes on Windows along with the stack backtrace.
On Linux (fedora 21 at least), the necessary function to enable
capture is not included in the system wx libs. But, a self built
version works fine and capture the backtrace, so I'm assuming
other distros will probably work as well.
On OSX, the crashes are caught, but it does not include the
backtrace.
But, really, the backtraces aren't all that useful in a release
build since we don't ship with debug symbols and optimization
plays havoc with proper backtraces anyway.
The real benefit will be for the support folks as they can now
get consistent info from user by asking the to generate a report
from the "Help->Generate Support Data" menu item.
In particular, use an options structure for AudioIO::StartStream to simplify
calls
ControlToolBar::PlayPlayRegion also takes that structure as an argument, and a
SelectedRegion instead of two times
And other changes
This brings the builtin, LV2, and VAMP effects inline with the
Audio Units, LADSPA, and VST effects. All effects now share
a common UI.
This gives all effects (though not implemented for all):
User and factory preset capability
Preset import/export capability
Shared or private configuration options
Builtin effects can now be migrated to RTP, depending on algorithm.
LV2 effects now support graphical interfaces if the plugin supplies one.
Nyquist prompt enhanced to provide some features of the Nyquist Workbench.
It may not look like it, but this was a LOT of work, so trust me, there
WILL be problems and everything effect related should be suspect. Keep
a sharp eye (or two) open.
A 4hr track used to take about 20s to cut a few samples. This is now significantly improved, to around 3s. Leland did this by
(a) moving the size calculation to when we examine the undo history, so it isn't slowing down the edits.
(b) in size calculation, using sizes that are cached rather than going to disk to find the sizes.
(c) writing the autosave file which is to an FFIle to a string first, i.e. using XMLStringWriter as a buffer for XMLFileWriter.
Step (c) may also make autosave marginally safer, as the risk of a partially updated autosave file is reduced.
The problem was that on Linux (not Windows or Mac) menu
events are generated when checking the menu items in
the toolbar menu.
Becuase of the recent changes I made and how the toolbars
are being shown (toggled) when the toolbar menu is checked,
they were simply being hidden. Actually, the were being
shown and then hidden because of the toggle.
So, with this change I made exposing toolbars a bit more
deterministic. The menus still use a toggle, but the
ToolManager now shows or hides the bars explicitly during
setup, so the menu toggle issue is resolved.
It corrects several "multiple project" problems with the
meter toolbars and meters.
In addition, there was a "multiple project" issue where
the transport buttons didn't disable properly in the
non-active project.
It never really worked right on GTK and MAC, so remove all of the
specific code for them and just allow it to work on Windows until
a correct solution is found.
(GTK and MAC have their own cycling key combos anyway)
