Enable FBO support; fix a couple bugs.
Enable framebuffer object support. I'm starting to see the value of
GLEW, but the implementations available don't handle GLES very well. A
primitive attempt at cross-platform compatibility at the source code
level was attempted, but the Correct Solution is runtime adaptation.
Fixed a bug in PCM.cpp; it now properly scales int16_t values to the
range -1.0 - 1.0.
Fixed a bug in Renderable.cpp; 'size' can be zero, leading to an attempt
to allocate and render a buffer of zero size. While the code correctly
handles zero-sized buffers, it's better to avoid it entirely.
