_Pool. Hop in, the water's warm._
Pool is a lightweight web-enabled multipurpose engine for UI apps and multiplayer games with physics designed to push the boundaries of what defines a contemporary user experience.
Pool is a lightweight web-enabled multipurpose engine for UI apps and multiplayer games with physics.

a: resize window resolution // todo: idk why it's ignoring me
b: resize projection // done: made eye.rs write to eye buffer
currently when you resize the window the projection matrix is not updated
and therefore it gets very skewed and weird looking if you resize the current
