	x, y, w, h: th.fu
}

A set of points representing a rectangle.

fn mk*

fn mk*(x, y, w, h: th.fu): Rect {

fn toWorld*

fn (r: ^rect.Rect) toWorld*(p: th.Vf2): th.Vf2 {

translates screen coordinates to world coordinates with cam r

fn toScreen*

fn (r: ^rect.Rect) toScreen*(p: th.Vf2): th.Vf2 {

translates world coordinates to screen coordinates with cam r

fn getPos*

fn (r: ^rect.Rect) getPos*(): th.Vf2 {

fn getDims*

fn (r: ^rect.Rect) getDims*(): th.Vf2 {

fn getEnd*

fn (r: ^rect.Rect) getEnd*(): th.Vf2 {

returns where the second point of the rectangle lies.
