edit null asset a bit to make it actually null
generate the tile meshes..but don't do anything with them yet
size down the player to (40, 50)px. that's a more fitting size for

this game, i think. terraria's is about that, and their size is nice.
cleanup
oh neat it scrolls, i was using the wrong var index for the block

it's not smooth tile scrolling yet though, i'm going to use an offset
for that
woot! per-pixel smooth tilemap scrolling
make the sprites hint dynamic drawing
adding zooming via +/- keys, but it's not supported at all right now

aka doesn't work right. as in it'll screw up tilemap game logic, since
that's tile based and doesn'ta ccount for different sizing
rm dead code
oops, indices should be static draw hint
