When FileChooser instances were created, launched, and hidden all inside
the same event callback on macOS 12.0.1, the chooser dialog sometimes
remained open. This could cause problems including crashes, as closing
the dialog would attempt to call a completion handler block referencing
an already-deleted FileChooser::Native instance.

Opening the chooser panel later on the message thread seems to resolve
the issue.

In stripped plugin builds, the repostCurrentNSEvent function was still
public. There doesn't seem to be a good reason for this, as no host
should need to call the function.

It looks like the shared code component of a Projucer-generated plugin
project was briefly built as a framework that was shared by the
different plugin wrappers. In this scenario, the framework would need to
make repostCurrentNSEvent public so that the wrappers could locate the
function. However, now that the shared code target is built as a static
library, standard external linkage should be sufficient for the symbol
to be located from the wrapper's TUs.

This fixes an issue on iOS platforms where the version number string is
prefixed with "OpenGL ES " despite the Khronos docs for OpenGL ES
specifying that "The GL_VERSION and GL_SHADING_LANGUAGE_VERSION strings
begin with a version number".

This mirrors the behaviour on Linux, where maximizing a window always
fills the screen, even if a constrainer is active.

If you don't want to allow your component to fill the screen, disable
the maximize button in the window's titlebar when creating the window
(i.e. ensure DocumentWindow::maximiseButton is not set in the required
buttons).

Previously, right-clicking on a slider could change its value, but the
parameter value would not be changed, leaving the slider in a different
state to the parameter.

This fixes a bug where selecting "Always on top" in the plugin editor
window in Cubase 11 on Windows 11 on a display with > 100% scale would
cause the editor to display with the wrong scale factor.

It seems that Cubase calls removed() then attached() on the plugin view,
destroying and recreating the editor wrapper component. The editor
opened with 100% scale, but requests from the host to set the "real"
scale factor were ignored because the JUCE wrapper thought that the
requested scale had already been applied.

Applying the cached scale factor directly after constructing the editor
keeps everything in a consistent state, and seems to resolve the issue.

When opening the "settings" menu of Arturia Pigments VST2, the editor
window would move itself over the JUCE non-native titlebar in the
AudioPluginHost. Then, when the editor was moved back into the correct
location, the titlebar would not be redrawn, leaving it in an incorrect
state.

This change forces a repaint of the editor's peer whenever the size
changes, forcing the titlebar to repaint after the editor has moved.

This fixes an issue where specifying an audio device type before calling
initialise could cause a different device to become active, even if the
requested device type had usable devices.

With this change in place, a new device type will only be selected if
the current device type has no devices.

This ensures that solution files have correctly numbered icons in
Windows Explorer.
