C++: Attempt to get dwtestoo working with old pre-lambda compilers.
Fixed a number of errors regarding this from the last commit, however...
GCC 4.2 errors out complaining about forward declaration of class Pixmap.
This forward definition is necessary to define some classes that reference
each other.  The issue seems to be these old GCC implmentations expect...
that these classes be defined in different files.  Since I forward declare
Pixmap before defining Render which uses it, then when I go to define
Pixmap, it is already forward declared and gives errors.  This code
is legit, but the compiler implementation is erroring out....
Not sure how to fix this right now without defining them in separate files.
