 > I think it would be best to keep the linear heap as small as possible so
 there's always more general memory available. It feels a bit impractical
 to have to adapt non-TinyGL engines to use custom allocators, and it seems
 that linear memory has the additional downside that it's easier to
 fragment when lots of stuff is allocated and freed.

 there are still a couple of candidates for reducing memory usage - one is
 to provide smaller formats for internal texture/image storage, and the
 other is to reduce the amount of memory needed by the LinearAllocators on
 a per-game basis. This should help on other platforms with limited memory
 as well, not just the 3DS.

 Sorry I'm late. I patched in your PR and compiled it. Unfortunately, the
 CIA version instantly crashed on my New 3DS. I have not had a chance to
 try the 3dsx version.
