These stats don't make sense right now.

It's nice to have an explicit action for presentation.

bjorn 89312c1c4b Add on-disk shader cache;
Set t.graphics.shadercache to true (the default) and lovr will
read/write a shader cache file from/to disk.

bjorn 4ee092e81b Make Pass a regular object;
It uses newPass instead of getPass.  Temporary objects had lifetime
issues that were nearly impossible to solve.  And normal objects are
easier to understand because they behave like all other LÖVR objects.

However, Pass commands are not retained from frame to frame.  Pass
objects must be re-recorded before every submit, and must be reset
before being recorded again.

Pass objects now provide a natural place for render-pass-related info
like clears and texture handles.  They also allow more information to be
precomputed which should reduce overhead a bit.

It is now possible to request a stencil buffer and antialiasing on the
window and headset textures, via conf.lua.

lovr.graphics.setBackground should instead set the clear color on the
window pass.  Though we're still going to try to do spherical harmonics
in some capacity.

There are still major issues with OpenXR that are going to be ironed
out, and the desktop driver hasn't been converted over to the new
headset Pass system yet.  So lovr.headset integration is a bit WIP.

bjorn c4ff7cca39 Passes track their readbacks;
There are some issues with immediately tracking readbacks in the global
linked list of pending readbacks:

- The Pass might not get submitted, in which case the readback will be
  "dangling" and never complete (or it will erroneously think it's
  completed but its buffer will contain garbage data).
- Thread safety issues of modifying a global data structure from a Pass.

Instead, Pass will locally track the readbacks it performs, and only at
submit time will those readbacks get added to the global list.

(There is a little bit of refcounting mistakes now, those will get
cleaned up).

This stuff is really confusing

bjorn 4e92a4e503 Super ultra cool geometry cache;
Pass stores a small 16-bucket cache of vertices/indices it recently
generated.  Draws that have relatively predictable geometry can provide
a hash along with their draw.  The Pass will reuse vertices based on the
hash, when possible, and return a NULL vertex pointer to let the draw-er
know they don't need to generate any vertices.

This provides a dramatic speedup when drawing the same shape many times
in a row.  The overhead is negligible, with benefits kicking in with
just a small handful of repeated draws (3-5 for cubes, less for more
complex shapes).
