The trapezoid now throbs between black and white. This was made to
test out the element buffers using MyBatch. Next up for the
batches should probably be to figure out the recommended way of
specifying more than one element buffer. Currently it is done
by specifying the number of elements to be stored and the number
of element vbos needed but maybe there is some way to get it to
work using variadic templates. There is a comment about this in
the Batch.h file.
Now batches are actually batches.
Also added the MeshFactory class.
Drawing modes are now specified with DrawMode instead of the
GLenum. Renderables must be specified with a draw mode.
This commit gets creates the ObjectOriented scene and gets it
working.
The current test program swaps a triangle from small to large with
the 1 and 2 keys on the keyboard. (1 for small and 2 for large).
The small triangle is rendered by the simple scene and the large
one is rendered by the object oriented one.
