/*
The pic class is tricky.

It is used to display full screen pictures (for isntance, diagrams).
We want the picture to take as much space as possible on the slide.

But we have two problems here:
- some pictures are taller than wide, others are wider than tall;
- some pictures are displayed by themselves, others with a title.

This makes it particularly difficult to resize the pictures. If we
set an absolute width or height, it won't work for both taller and
wider pictures. If we set an absolute height, it won't work with
both pics-with-title and pics-by-themselves.

Perhaps it would be a good idea to replace the pic class with two
different classes, like pic-with-title and pic-by-itself; but in
the meantime, we'll check if the <img> tag is within the first <p>
in the slide to try and guess if the pic is by itself, or with
a title. It won't be 100% bulletproof but it should work for
our slides.

The pixel dimensions in the classes below correspond to the base
scaler dimensions of remark (see scaler.js in remark source code).
