convex hull proto with line/poly intersection stub
remove intersection stub
add convex hull via upper/lower tangents
change debug page
check cw and ccw via vectors cross product
convex hull done without refactoring
refactor convex hull
begin concave implementation
draw concave hull with constant dencity and too slow
manual angle and distance tuning (we need to do that automatically)

change angle calc to cos calc
decrease sqrt calls
cleanup code after trigonometry battle
add experimental bbox perf improvement
increase angle to 90 degs and comment _intersect checking
