* 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

py3 fix for ScatterPlotWidget.setSelectedFields

Image axis order bugfix

This issue was introduced in merging develop into #1175.
While refactoring for the merge, the change in namespace was not
correctly attributed, leading to the parameter `opts` to be assumed
in local namespace when it isn't.

Using `opts` as alias for `self.param.opts`, following the style of `updateFlags`.

ParameterTree: Fix custom context menu

- Adds doc strings for user-facing methods so they appear in the
  documentation.
- Allows PlotItem.addLegend to accept the same arguments as LegendItem
  constructor for convenience.
- Fixes a bug for adding a BarGraphItem (which doesn't have an antialias
  option) to LegendItem

Minor improvements to LegendItem

Wrap text in tables in docs

LegendItem: A bit auto flake8

* SignalProxy: Correct initialization without slot argument and provide tests

* Add missing slot is None case on disconnect

* Start new tests

* Exception block

* Test no module

* Different signal

* Debugging the signal connect

* Re initialize proxy after disconnect

* Add more test cases for blockSignal

* Change test case for signal count

* Give up for python 2 and pyside

* Exclude for Python 2.7 and PySide

* Convert float to integers in timer start period

* Add "lstep" and "rstep" step Modes

stepMode is currently either True or False. If it is True,
it requires the user to make len(x) = len(y)+1. This is
inconvenient because it makes it difficult to change the
stepMode on a given curve (just as one would change, e.g.,
its color).

This commit extends the current situation by introducing
two more step modes: "lstep" and "rstep", which do not require
passing an extra x value. In turn, this modes associate each
y value to either the left or the right boundary of the step.

For example, the "rstep" mode is handy when plotting "life"
digital signals in which x,y data pairs are appended as they
are read.

This commit does not modify the behaviour in case of stepMode=True

* Replace step mode names: lstep,rstep -> left,right

* Improve docs for stepMode

Reword docstring and add it to PlotDataItem class too

* Document left and right stepModes as added in v 0.12.0

TODO: confirm the exact version number to use here

* Add comments stress the need for "is True"

Some conditional statements in the code regarding stepMode are
done with "is True". This is actually required since other
possible values such as "left" also evaluate as true but should
not be caught.

* Deprecate boolean API for stepMode

Introduce stepMode="mid" as a replacement of stepMode=True,
but keeping full backwards compatibility with the old API.
Adapt docs, examples and tests accordingly.

* Raise ValueError on unsupported stepMode values

* Rename "mid" step mode to "center"

* Remove "added in 0.12.0" note

See #1360 (comment)

* Add deprecation warning when stepMode=True

Issue a DeprecationWarning if stepMode=True is being passed to the
constructor or setData() of PlotDataItem or PlotCurveItem.

Note: warnings module is imported locally so that it is esier to
remove once this check is no longer needed.

* Fix wrong syntax in last commit

Fix usage of "default" kwarg in dict.get()

This commit adds a depth buffer in renderToArray().

This fixes the issue that overlapping objects are rendered incorrectly
when using renderToArray() on a GLViewWidget.

This might be related to issue #743.

* Call GraphicsItem.viewTransformChanged()

* Needed to apply to labels too

Harmonizes behavior with PlotCurveItem.

- Parameters now respond to title change in setOpts
- Add Parameter.title()
- Action parameter uses default name/title handling in addition to setting button text (fixes #1320)

The three parameters "shape, vectors, origin" can't be passed as parameters because they are computed, which raise an error when kwds is passed to affineSlice.

Bounds are enforced against inf and -inf inputs, but not for nan.

* Make inf and nan entry in SpinBox case-insensitive

* Make SpinBox example behave as advertised

* Make non-finite SpinBox values optionally allowed
