No changes, just cleanup the image part of the docview sample.

Remove unnecessary, never used methods.

Don't use pointers when objects or references can be used more safely.

Don't name classes which are not part of wx with "wx" prefix to avoid
confusing people.

Don't define empty unnecessary event tables.

Prefer wxScrolledWindow::SetVirtualSize() to SetScrollbars().

Stop using "protected" when "private" should be used.
