A TDD test to check we can set the theme from a user-defined stylesheet.For this, just use Solarized_Light2.
... with their own custom stylesheet. At the moment this must be called'user.mplstyle' in the cwd.
Follows on frommatplotlib#2 andmatplotlib#86. We can remove the hard-coded theme setup andmove to using matplotlib stylesheets (napari-dark.mplstyle andnapari-light.mplstyle) instead. The caveat is that this means the pluginis _less_ flexible when presented with a weird and wonderful user theme.

Here is where we're now less flexible. I figured we should fallback to the default mpl style ☝️
We could also do something more complicated withself._theme_has_light_bg
and choosing a light or dark mpl style to contrast.
Closing in favour of#175 |

A dependent draft PR (sorry!) following on from#156.
Only pay attention to6166de7 (the previous two commits should disappear after rebasing).
Summary
Wecould copy the dark and light napari themes as mplstyle files and match the theme to the plot style.

Reviewer notes
We mightnot want to do this: it would mean that we're less flexible when a user defines their own napari theme (the previous way, of interrogating the
napari.theme
to manually set plot style was agnostic to whether the napari theme was stock or custom).On the plus side: the code is simpler, and it separates aesthetics from function.
