  wxGUI: fix inconsistent layer sizes during rendering (#552)

Passes environment with width and height throughout the rendering process
to ensure consistent size.

Before rendering, checks already rendered layers have consistent size with
new size, if not, forces them to rerender.

After g.pnmcomp during checking vector legend changes, only render when
there is an actual vector legend overlay present.
