27c862970b Simplify sprite management code
Now if decorations are needed they are created *before* the index for
the sprite is assigned.

b2a4db2028 Revert metadata row for sprites
Store in a separate VAO instead more performant as it uses less VRAM and
allows shader lookup co-ords to be passed to fragment shaders without
calculation in the fragment shader.

5d195bf50b Give sprites a metadata row accessible in the shaders
Will allow sprites to point to where their decorations should be read
from, for instance. Needed for scaled text and also if we want to
implement decoration avoidance.

0fb49f4139 Switch to using an index for sprite tracking
Frees up two bytes in GPUCell. Doesn't require a minimum texture row
size. Makes a bunch of code faster. Index uses 31 bits which gives us
2,147,483,647 aka ~ 2 billion sprites.
