A.Canvas now uses kdtree to get nodes closest to player working out
B.during firing up a bubble is loaded in once the edge is reached, the
load order swaps on the kdtree return bubble (avoiding ittering the center again)
c.when a tile unloads the data is saved
d.when you quit all active tiles are updated and saved
e.New 'Spraypaint' system is in!
vertex color 0 ->.5 = splat mapping
vertex color over .5 'throws the bloom switch'
for Effects later like highlighting paths or energy weapon damage :D
