Radium 6.9.97 released

[Kjetil Matheussen]

This is a big release with lots of improvements and bug fixes. The
version number has only been bumped one step though, to lower the risk
of having to make 6.9.1xx or 6.10.xx releases before Radium 7.

The biggest bug fix this time might be fixing the space and return
keys for playing and stopping, which was not always working before on
faster computers.

Another big improvement is making sure Radium now looks good on high
DPI screens. It was usable before though, but many dialogs and widgets
were wrongly sized in various ways.

Another improvement is that a new and configurable keybinding can be
used as a mouse-delete button, as an alternative to pressing Shift +
Right button. By default, the ZL1 key (placed one step left to Z on a
QWERTY keyboard) is assigned for this task.

There have also been many improvements to how the program handles
mouse in general, and many popup menus have been improved. This is
where most of the development time has been spent.

Besides this, the release contains several bug fixes and some new
minor features. See changelog below for all the details.


Changes 6.9.96 -> 6.9.97:
* Linux: Removed libglib-2.0.so from the Linux
binaries since it sometimes caused 3rd party
plugins to fail loading. (Caused by conflicting
libraries)
* Linux: Update included system library files.
* GUI: Fix making Shift + Right mouse button reset
mute and solo in the sequencer.
* Plugin scanner: Fix displaying error messages on
Linux and Windows.
* JUCE: Update JUCE to 6.1.4. This might fix various
issues with VST3 on Linux and other things.
* Plugins: Fix crash when selecting the "Set ..."
option in the effect popup menus.
* GUI: Lots of high DPI fixes. The whole program
should look descent on high DPI screens now.
* Audio preferences window: Support high DPI
screens. (Probably not working on macOS though...)
* Plugins: Support high DPI screens for the GUI for
plugins. (Probably not working on macOS though...)
* Keyboard: Workaround to fix space and return keys
not always working (especially on newer and faster
computers).
* Startup: Fix custom python code added in the
keybinding configuration file sometimes not working
(especially on newer and faster computer).
* Demo songs: Fix sweeping filter automation in the
main demo song.
* GUI: Lots of mouse handling improvements.
* GUI: Make the "ZL1" key (i.e. the key one step to
the left of "Z" on a QWERTY keyboard) behave the
same way as pressing Shift + Right mouse button.
* GUI: Make the mouse "Back button" (for mice having
this button) behave the same way as pressing Shift
+ Right mouse button.
* Menus: If a function has more than one shortcut,
display the shortest of those shortcuts in popup
menus.
* GUI: Improve various popup menus.
* Instruments: Don't create a new undo entry when
resetting an effect and the effect already had the
default value.
* Linux: Fix scheme listener not always starting
unless running on Ubuntu 18.
* Preferences/Audio: Add option to not use JACK even
when JACK is running.
* Audio: Fix possible problems when initializing JUCE
audio.
* Playlist: Don't show error message if pressing the
delete key in an empty playlist.
* Editor: Make it possible to assign keybindings to
the "New Sample Player" and "New MIDI Instrument"
options in track header menu.
* LADSPA/Windows: Another attempt at preventing
windows from scanning the included ladspa plugins
during startup. It doesn't seem to always work
though. The built-in virus scanner in Windows seems
to be extremely aggressive. The LADSPA files are
never opened or read during initialization.
* Demo song: Fix low pass filter automation.
* Editor: In the pianoroll header, fix "A" button not
always behaving quite correctly.
* Audio: New song properties option for muting output
of the 5 system buses when a plugin is bypassed. By
default this option is ON for new songs and OFF for
old songs (to keep kompatibility).
* Manual: Add recipe to the Mixer FAQ on how to
create a sidechain compressor.
* Manual: Add how to set volume higher than 6db in
the mixer FAQ.
* Editor: In the "(click me)" menu, display currently
used audio instruments before currently used MIDI
instruments.
* Edit: Also expand/shrink end pitch value when
expanding/shrinking pitch.
* Edit: Fix expand/shrink pitch. Last release wrongly
assumed end pitch always had a legal value.
* Plugin Info box: Inform when a mono LADSPA plugin
has been automatically transformed into a stereo
plugin.
* API:
* New: setMuteSystemBusesWhenBypassed,
muteSystemBusesWhenBypassed, setPianorollRange,
simulateDeleteMouseButton,
gui_rerunLastMouseEvent,
hasEventConnectionUnderMouse,
hasAudioConnectionUnderMouse,
getEventConnectionUnderMouseSourceInstrument,
getEventConnectionUnderMouseDestInstrument,
getAudioConnectionUnderMouseSourceInstrument,
getAudioConnectionUnderMouseDestInstrument,
gui_getGfxScale.
* minimizeBlockTracks: Optional argument "force".
