+Subject: [PATCH] Fix TypeErrors with Python 3.10
+
+Without these changes, running Picard with Python 3.10 results in errors
+such as:
+  File "./picard/ui/coverartbox.py", line 74, in __init__
+    self.shadow = self.shadow.scaled(w, h, QtCore.Qt.KeepAspectRatio, QtCore.Qt.SmoothTransformation)
+TypeError: arguments did not match any overloaded call:
+  scaled(self, int, int, aspectRatioMode: Qt.AspectRatioMode = Qt.IgnoreAspectRatio, transformMode: Qt.TransformationMode = Qt.FastTransformation): argument 1 has unexpected type 'float'
+  scaled(self, QSize, aspectRatioMode: Qt.AspectRatioMode = Qt.IgnoreAspectRatio, transformMode: Qt.TransformationMode = Qt.FastTransformation): argument 1 has unexpected type 'float'
