* Trying translate on exporter strings
* Try translate on other misc context menu strings
* First f-string and I screw it up...
* add more translation calls
this lets us support the various bindings w/o having to add binding
specific code.
it breaks PyQt4 support since PyQt4 template files are suffixed as
"_pyqt" rather than "_pyqt4"
QFont.setBold(True) calls QFont.setWeight(QFont.Weight.Bold)
in Qt 5, QFont.Weight.Bold == 75
in Qt 6, QFont.Weight.Bold == 700
in PySide6, QFont.setWeight() no longer accepts an integer value.
* Do not wrap PlotView/ImageView
There is no need to wrap PlotView/ImageView into QMainWindow, since
only purpose of the QMainWindow is some default menu toolbar & menu
handling, that is not used by PyQtGraph anyway.
Moreover, every parent-less Qt widget can become window, so this
change just use PlotView/ImageView as windows, removing extra
complexity, eg. method forwarding, self.win property.
Another benefit of this change, it that these windows get initial
dimensions and titles as they were designed in .ui file.
* Properly cleanup on ImageView.close()
We should not close explicitly child widgets or clear scene, otherwise
Qt will deallocate children views, and cause "wrapped C/C++ object of
type ImageItem has been deleted" error next time we call close()
and/or some other methods.
All children, including self.ui.roiPlot, self.ui.graphicsView will be
closed together with its parent, so there is no need to close them
explicitly.
So the purpose of close it to reclaim the memory, but not to make the existing ImageView object dysfunctional.
* Remove references to plot & image windows after close
PyQtGraph images and plots module list variables are currently holding
references to all plots and image windows returned directly from main
module. This does not seem to be documented however, and causes the Qt
windows to be not released from memory, even if user releases all own
references.
This change removes the references from images/plots list once window
is closed, so when there is no other reference, window and all related
memory is reclaimed.
* Change all UI forms title from Form to PyQtGraph

Pull request #907 addressed a specific case where a signal was emitted before a state update.
If an application's slot then calls back into the instance, the instance was in an inconsistent
state. This commit audits and fixes similar issues throughout the pyqtgraph library. This
commit fixes several latent issues:
* SignalProxy: flush -> sigDelayed -> signalReceived would have incorrectly resulted in timer.stop().
* ViewBox: resizeEvent -> sigStateChange -> background state
* ViewBox: setRange -> sigStateChange -> autoranging not updated correctly
* ViewBox: updateMatrix -> sigTransformChanged -> any _matrixNeedsUpdate = True -> ignored
* Parameter: Child may have missed state tree messages on insert or received extra on remove
* GraphicsView: updateMatrix -> sigDeviceRangeChanged/sigDeviceTransformChange -> before propagated to locked viewports.
Moved eq function from flowcharts to main function library to support this.
Bonus: fixed a flowchart bug (backspace deletes wrong connector) while I was in there.
