This also re-enables the splash screen and recombines the
OnInit() and FinishInits() since I'm pretty sure the progress
dialog was the issue.
I also retested (as much as I could) and cleaned out all of the
little "hacks" the progress dialog gained over the years. With
the new modal handling of wx3, it seems that things are much better
behaved.
However, it seems that wxGTK (at least) has gained some new focus
probs (to be dealt with later).
... and anticipate a problems fisheye will introduce with time ruler display
and horizontal scrolling past zero.
Will be used in waveform and spectrogram drawing, and in hit-test for sample
editing. Those things will no longer make the assumption of uniform zoom
level across the width of the screen, though that does remain true without the
rest of the fisheye project.
... and SelectedRegion, and not ViewInfo or zoom level as a double.
Also some leftOffset arguments.
Assumptions of uniform zoom level persist in TrackArtist::DrawClipSpectrum and
in TrackArtist::DrawClipWaveform but no longer in the rest.
... miscellaneous direct uses of ZoomInfo::zoom to test and set zoom level.
This includes all the remaining assignments to it.
But moving TrackInfo::PositionToTime and TrackInfo::TimeToPosition into
ZoomInfo and using them is needed to eliminate many more uses.
Also #if'd out the unused AudacityProject::OnZoomToggle().
... With a careful sweep of uses of WaveTrack::GetDisplay() to remove
assumptions about the ordering of the values.
Using < and <= on enum values is mostly a bad idea.
wx3 on OSX has changed how the mouse wheel delta is calculated. Prior
to wx3, it was simply set to 1 so the wheel rotaion value was simply
increments of one.
With wx3, higher resolution devices (like touchpads) are supported so
the value for wheel rotation can be a fraction of the delta, so it is
possible to pass a zero value to the NumericConverter::Adjust() method.
Therefore, the method just returns in this case.
Caused by fix to Bug 844 not initialising mIsCapturing to false. So play-at-apeed could mistakenly think recording was in progress, and so prevent play-at-speed.
configure script now auto detects whether wxWidgets was built using
gtk2 or gtk3, so there's no longer a need to specify which one when
running configure.
VST support updated for wx3 under GTK.
