Control for plugin enabled, for convenience.

This port is already in Plugin::in_ports.

Control for plugin gain, for convenience.

This port is already in Plugin::in_ports.

Whether the UI has finished instantiating.

When instantiating a plugin UI, if it takes too long there is a UI buffer overflow because UI updates are sent in lv2_plugin_process.

This should be set to false until the plugin UI has finished instantiating, and if this is false then no UI updates should be sent to the plugin.

State directory (only basename).

Used for saving/loading the state.

The Plugin's window.

This is used for both generic UIs and for X11/Windows when plugins are wrapped.

All VST plugin UIs are wrapped.

LV2 plugin UIs are only not wrapped when they have external UIs. In that case, this must be NULL.
