Pass gfx structs by const ref (gfx::Vector2d)
Avoid unneccessary copy of structures gfx::Vector2d
by passing them by const ref rather than value.
Any struct of size > 4 bytes should be passed by const ref.
Passing by ref for these structs is faster than passing
by value, especially when invoking function has multiple parameters.
