* Many unused import cleanups
Ignored some star imports, some vendored code in colorama, only looked within pyqtgraph the library, not e.g. examples
* SpinBox decimal imported with both import and from import
Significant performance issues have been identified with np.clip
and thus clip_array was created to speed up the operation. In addition
clip_scalar was created to clip a scalar value between two other values
this commit replaces many uses of np.clip from operating on scalars to
using clip_scalar instead
* 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"
* 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

* py3k: Remove reduce calls.
* py3k: Remove compatibility sortList function.
Sorting by key has existed since Python 2.4.
* Remove unnecessary sys.path manipulation.
This file doesn't have any __main__ code to run anyway.
* Use context manager
