`QRect`/`TypeError` regression introduced by PyQt5 version 5.15.7
After updating to PyQt5 version 5.15.7, it is possible for Gridsync's BadgedPixmap to throw TypeError as follows:
Traceback (most recent call last):
File "/home/user/code/gridsync/gridsync/gui/main_window.py", line 305, in on_message_received
self._maybe_show_news_message(gateway, title, message)

rect = QRect(
TypeError: arguments did not match any overloaded call:
QRect(): too many arguments
QRect(int, int, int, int): argument 1 has unexpected type 'float'
QRect(QPoint, QPoint): argument 1 has unexpected type 'float'
QRect(QPoint, QSize): argument 1 has unexpected type 'float'
QRect(QRect): argument 1 has unexpected type 'float'
The relevant code path shows that, depending on the size of the base image, BadgedPixmap can, indeed, pass a float to the QRect constructor, leading to the above error. Accordingly, these values should be cast to ints so as to avoid throwing a TypeError.
