sort of the start of a diamond player box now
actually a diamond now
add another vert to this..i don't think this can scale well

i'm thinking that using 2 circles..or 3 is a better approach for the
character bodyies.
player body now formed by 2 circles
cleanup and fix the position of the lower circle
physics bodies are now very tuned. they're very hardcoded though

but i suppose in a  way, they kidn of have to be. for the player, anyways.
fix tabs so that they don't do weird line wrapping (the tab buttons)

and so that i can actually navigate them
more tab fixes..
fix tab panel height
i'm not happy with the tab handling, but it works..

also, do a temporary border solid line outline so we can see where the
tabs are, since we have no graphics for them yet.
add debug settings tab renderer checkboxes, to enable rendering of

various areas..like tile, lighting, box2d shapes, joints, AABBs, etc.
added tab with contents to toggle various gui debug rendering bits and

bobs. so we can now toggle on/off various box2d debug rendering stuff
remove the individual variables for renderable toggleables and now

just check for the specific flag in the bitfield..much cleaner, and
all consolidated to the gui and the settings thingy
