Replace glContainer with glAllocator

glContainer is no longer required, as we can use std::vector with a
custom allocator which uses OpenGL buffers for storage. Minor irritation
is that the mapped buffers aren't guaranteed to be flushed in the tests,
so sometimes we're missing bits in a test render.
