and memcpying it does.
This commit also contains some code protected by #ifdef DXA_EXPERIMENT_MAXD
that allows for reading an extended header on a .dxa file and using a MAXD
chunk, if found, to reduce the amount of memory required to play a movie.
Whether this gets enabled or not will ultimately depend on whether the savings
are justified (i.e. if we can find a case where it makes enough difference).

unscaled frame when playing a scaled movie. (The Broken Sword 1 intro is a
good example of this since it is scaled and uses NULL frames early on.)
svn-id: r24870
entire buffer.
Introduced a _drawBuffer pointer which points either to _scaledBuffer or
_frameBuffer1. That way, we don't need to copy _frameBuffer1 every time we
draw an unscaled frame. (Probably the most common case by far.)
Adjusted the Broken Sword 1 DXA player for the second change. (It sneakily
avoids copying each frame by using _drawBuffer directly.)
