The use of VisPortChgd ensures that the tiles all render as
expected, i.e. that the pixels match 1:1 irrespective of actual tile
size (for identical zoom factors and document areas).

Using SetVisArea can cause problems due to various internal
state getting confused, however this gives correct output
without viewport assertion problems or missing content.

This reverts commit ff6a38b7.

This is a real problem, which is fixed in a following commit -- tiled
rendering does not currently set the viewport at all, which can result
in an empty (or otherwise incorrect viewport), so this assert is definitely
valid.

This reverts commit fb0b42b8.

New warning from Clang 6. So get rid of the initWithOUString
initializer completely, it is called only from stringWithOUString
anyway.

Handlers are conceptually stateless; we can keep them as const objects.
