In Python 3.10, a change[1] was implemented where extension functions
that take integer arguments will no longer silently accept non-integer
arguments (e.g., floats) that can only be converted to integers with a
loss of precision. This PR fixes most of these issues in the pure-Python
classes and demos by explicitly converting the parameters to int before
passing them to wxWidgets. There is loss of precision, but this was
happening before (automatically) anyway as most wxWidgets DeviceContext
functions operate using integers.
Additionally, the PR fixes a few sizing issues, mostly with SpinCtrls being
too small on GTK3.
This is an example of the relevant exception:
Traceback (most recent call last):
File "/usr/lib64/python3.10/site-packages/wx/lib/agw/pygauge.py", line 355, in OnPaint
r.width = w
TypeError: 'float' object cannot be interpreted as an integer
Fixes #2038.

wx.lib.plot
A simple, light-weight plotting package for wxPython Phoenix.
Based on wxPlotCanvas Written by K. Hinsen, R. Srinivasan; Ported to wxPython: Harm van der Heijden, Feb 1999
This is a simple, light weight plotting module that can be used with Boa or easily integrated into your own wxPython application. The emphasis is on small size and fast plotting for large data sets. It has a reasonable number of features to do line and scatter graphs easily as well as simple bar graphs. It is not as sophisticated or as powerful as SciPy Plt or Chaco. Both of these are great packages but consume huge amounts of computer resources for simple plots. They can be found at http://scipy.com
