Source code for ewoksxas.canvas

"""Canvas launcher for ewoksxas.

Thin wrapper around ``ewoksorange.gui.canvas.main.main`` that raises the toolbar
priority of the third-party ``orangecontrib.spectroscopy`` category before widget
discovery runs. We cannot edit that package's source, so we patch its category
module global here. Our own "X-Ray Spectroscopy" category sets ``PRIORITY``
statically in ``orangecontrib.ewoksxas.widgets``; only the external Spectroscopy
category needs this runtime patch.

Relies on ewoksorange's ``main`` force-appending ``--force-discovery`` (which
invalidates any cached registry), so the patched PRIORITY is read on a fresh pass.
