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.
