* Use the exactly same routines to deliver png images that are used in
mathml mode.
* Change the output to use mathoids png image rather than the mathml
and svg output.

the SVG or the PNG path is used.

The motivation for this patch is to make the code less complex, better
readable, and less brittle.
Example:
public function onExampleHook( Parser &$parser, array &$result ) {
/* This is the hook handler */
}
In this example the $result array is meant to be manipulated by the
hook handler. Changes should become visible to the caller. Since PHP
passes arrays by value, the & is needed to make this possible.
But the & is misplaced in pretty much all cases where the parameter is
an object. The only reason we still see these & in many hook handlers
is historical: PHP 4 passed objects by value, which potentially caused
expensive cloning. This was prevented with the &.
Since PHP 5 objects are passed by reference. However, this did not
made the & entirely meaningless. Keeping the & means callees are
allowed to replace passed objects with new ones. The & makes it look
like a function might intentionally replace a passed object, which is
unintended and actually scary in cases like the Parser. Luckily all
Hooks::run I have seen so far ignore unintended out-values. So even if
a hook handler tries to do something bad like replacing the Parser
with a different one, this would not have an effect.
Removing the & does not remove the possibility to manipulate the
object. Changes done to public properties are still visible to the
caller.
Unfortunately these & cannot be removed from the callers as long as
there is a single callee expecting a reference. This patch reduces the
number of such problematic callees.
