* Remove all usage of python2_3.py
Technically these functions were exported at the top level of the library, this removes them without warning... If we want to we can bring them back for there, but I honestly don't think its needed, as we are py3 only now and have been for multiple releases.
This may introduce a number of 'useless cast' or similar but those were always happening anyway

Various places in the library attempt to check if scalars are finite
via numpy methods, which are intended to be used on numpy arrays. Using
the math module equivalent functions on scalars is significantly faster.
In a few places, I also use numpy methods explicitly (np.all vs. all)
from the Qt documentation,
- "AlignCenter = AlignVCenter | AlignHCenter"
- "You can use at most one horizontal and one vertical flag at a time.
Qt::AlignCenter counts as both horizontal and vertical"
- "Conflicting combinations of flags have undefined meanings"
for AxisItem.py, from the code structure, it would appear that the
intent was to use AlignHCenter.
for ROI.py, AlignCenter == AlignCenter | AlignVCenter

To set the tick font of `AxisItem`s, there are two options:
`setStyle({"tickFont":...})` and `setTickFont(...)`.
The first option sets `AxisItem.style['tickFont']`, the second
sets `self.tickFont`. Only `self.tickFont` is actually used.
This PR replaces all occurrences of the second variable with the first
variable, so both options work again. Also, documentation from
`setStyle` is copied to `setTickFont`.

* Add DateAxisItem
* Change style to camelCase
* Fix missing first tick for negative timestamps
* Add ms precision, auto skipping
Auto skipping allows a zoom level to skip ticks automatically if the
maximum number of ticks/pt is exceeded
* fixes suggested by @goetzc
* workaround for negative argument to utcfromtimestamp on windows
* attachToPlotItem method
* default date axis orientation
* Use new DateAxisItem in Plot Customization example
* attachToPlotItem bugfix
* examples of DateAxisItem
* modified description of customPlot example
* added descriptions to the new examples, reformatted their code, included the first one into utils.py
* typo
* Refactored code for setting axis items into new function
Replaces "DateAxisItem.attachToPlotItem"
* Fix string comparison with ==
* Doc: Slightly more text for DateAxisItem, small improvement for PlotItem
* Make PlotWidget.setAxisItems official
* Fix typo in docstring
* renamed an example
* merge bug fix
* Revert "merge bug fix"
This reverts commit 876b5a7cdb.
* Real bug fix
* support for dates upto -1e13..1e13
* Automatically limit DateAxisItem to a range from -1e12 to 1e12 years
Very large years (|y|>1e13) cause infinite loop, and since nobody
needs time 100 times larger than the age of the universe anyways,
this constrains it to 1e12.
Following suggestion by @axil:
https://github.com/pyqtgraph/pyqtgraph/pull/1154#issuecomment-612662168
* Also catch ValueErrors occuring on Linux before OverfloeErrors
While zooming out, before hitting OverflowErrors, utctimestamp
produces ValueErrors (at least on my Linux machine), so they
are also catched.
* Fix: Timestamp 0 corresponds to year 1970
For large years, x axis labels jump by 1970 years if it is not
accounted for timestamp 0 to be equal to year 1970.
* Fix: When zooming into extreme dates, OSError occurs
This commit catches the OSError like the other observed errors
* Disable stepping below years for dates outside *_REGULAR_TIMESTAMP
2 reasons: First: At least on my Linux machine, zooming into
those dates creates infinite loops. Second: Nobody needs
sub-year-precision for those extreme years anyways.
* Adapt zoom level sizes based on current font size and screen resolution
This is somewhat experimental. With this commit, no longer 60 px are
assumed as width for all zoom levels, but the current font and
display resolution are considered to calculate the width of ticks in
each zoom level. See the new function `updateZoomLevels` for
details.
Before calling this function, overridden functions `paint` and
`generateDrawSpecs` provide information over the current display
and font via `self.fontScaleFactor` and `self.fontMetrics`.
* Meaningful error meassage when adding axis to multiple PlotItems
As @axil noted in the DateAxisItem PR, currently users get a
segmentation fault when one tries to add an axis to multiple
PlotItems. This commit adds a meaningful RuntimeError message
for that case.
* setZoomLevelForDensity: Refactoring and calculating optimal spacing on the fly
* DateTimeAxis Fix: 1970 shows when zooming far out
* Refactoring: Make zoomLevels a customizable dict again
* updated the dateaxisitem example
* Fix: Get screen resolution in a way that also works for Qt 4
This is both a simplification in code and an improvement in backwards compatibility with Qt 4.
* DateAxisItem Fix: Also resolve time below 0.5 seconds
* unix line endings in examples
* DateTimeAxis Fix: For years < 1 and > 9999, stepping broke
Stepping was off by 1970 years for years < 1 and > 9999,
resulting in a gap in ticks visible when zooming out. Fixed by
subtracting the usual 1970 years.
* DateTimeAxis Fix: Zooming out too far causes infinite loop
Fixed by setting default limits to +/- 1e10 years. Should still
be enough.
* improved second dateaxisitem example
* 1..9999 years limit
* DateTimeAxis: Use OrderedDict to stay compatible with Python < 3-6
* DateAxisItem: Use font height to determine spacing for vertical axes
* window title
* added dateaxisitem.rst
* updated index.rst

Currently `_updateMaxTextSize ` will increase the current space required for axis labels, if necessary, but not decrease it when the extra space is no longer needed. The proposed change will release no longer needed space again.
Issue where MouseDragEvent would only work for 1 AxisItem. Allowed the MouseDragEvent to propagate to other AxisItems. I had this issue by setting the ViewBox background color and changed the AxisItem ZValue to make the AxisItems visible which made the AxisItem receive all of the MouseDragEvents and only one Axis would actually allow dragging.
