Various performance improvements to pg.Point (#1741)
This change makes use of QPointF methods which perform faster than the python
equivalent methods.  Furthermore, some tests are added.

* Set __slots__ to empty tuple for pg.Point
* Make Point.angle() behave as Vector.angle()

Static code checker identified multiple places where a file is opened
but is not necessarily closed.  This commit addressed that with the
exception of RemoteGraphicsView.py

c4a1cf11a1 Use clip_array or clip_scalar instead of np.clip
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

b0a3849960 Use math module methods for singular values
Using numpy methods that are intended for vectorized operations is
substantially slower than using the math module, so when feasible the
math module methods should be used.

of Python 3.8, but that has not happened.

fda8731dab reduce memory usage during data generation
random.normal() generates as float64 and gets converted to a smaller
dtype. generating all the needed data in a single call thus uses a lot
more memory than is necessary.

this changes it such that smaller chunks are generated.
data clipping is also changed to be in-place.

the gaussian filtering which gave the video a washed-out look is also
removed. this also contributed to data generation time.

e09a397ebc modify environment to choose binding
the Example App allows the user to choose a binding and a graphics
system to use to execute an example.

issue 1: setGraphicsSystem is obsolete and the method no longer exists.
thus selecting a graphics system causes an error.

issue 2: the choice of binding to use is passed as an extra command
line argument to be parsed by initExample. this is problematic for
examples that use argparse, such as VideoSpeedTest.py

issue 3: if the user has set PYQTGRAPH_QT_LIB, that takes precedence
over the choice made in the Example App.

this patch fixes the above 3 issues by setting PYQTGRAPH_QT_LIB in
the child process' environment and removing the old parsing of the
command line arguments

LegendItem: fix docs & minor bugs (#1437)
* LegendItem: fix spelling mistake

* LegendItem: remove unused curRow variable

* LegendItem: correct calculation of rowCount

Previously, rowCount would never be updated unless setColumnCount()
was called. This fixes that issue.
It also fixes that setColumnCount() rounded down (floored) the
number of rows, instead of providing an accurate number:
e.g. 4 items in 3 columns would yield rowCount=1, when it should be 2

* LegendItem: remove rowCount argument (not implemented)

Logic to actually use the rowCount argument was not implemented.
Users might expect rowCount to limit the number of rows to e.g. 1,
but that is not what the current code does (it only works with limiting
the number of columns).
Thus, we were exposing an unused/misleading parameter to users.

This can and should be reverted if the logic for limiting the number
of rows is added.

* LegendItem: add colCount docs

* test (LegendItem): remove unused curRow variable

* test (LegendItem): check increasing rowCount as add items

* Fixed logic in placement of items in legend with multiple columns

* Actual row count here should be 2, not 3
