depending on the implementation, a zero-sized QPolygonF may not
have any underlying buffer allocated and may return a null pointer when
queried for its "data()"
this null pointer is returned to Python as a "None" which breaks code
not expecting it.
Huge thank you to @feketeimre for the initial PR for this feature
Thank you to @pijyoi for re-implementing with no changes needed to
GLViewWidget and supporting QOpenGLWidget vs. QGLWidget.
* feature More parameter item types
Pen: Pops up a dialouge that allows the user to customize a pen. Setting pen value is not working yet.
Progress bar: For indication things.
Slider: Easier way to set values that dont require precision.
Fonts: Picking font types. Next thing could be a Font dialog.
Calendar: For picking dates or intervals
Open/save file/files/directory: Pops up an open/save file/directory dialog to select a file/directory. Filter string and caption can be defined too.
A PenSelectorDialog widget was created for the pen parameter item too.
Also added these parameter items to the example.

* Remove the use of pyqtgraph.ptime
With us supporting python3.7+, we have no more need for the ptime module
and can instead safely use perf_counter for everything.
* Address small issues PR turned up
* Reword comment in ImageView

define opts['viewport'] to be in device pixels.
note from the removed comments that there was one place assuming
opts['viewport'] was in device pixels and the other assuming that it was
in device independent pixels.
1) no need to get rect(), which is actually defined as
QRect(0, 0, width(), height())
2) use col-maj data() instead of row-maj copyDataTo()
- glLoadMatrixf() takes col-maj
* draw GradientLegend in ViewBox coordinates
* some cleanup

* work in scenepositions so that detection also works in a layout
* added comments/remove debug statements
* un-busy as many times as needed
* lint
* add test to prove cursor behavior
* tentative change in the hopes that all supported qt versions behave properly
* remove unnecessary code
