overlaytext!(img, str::String, height::Int, bottomleft::Tuple{Int,Int};
        font::String="Courier",
        color::ColorTypes.RGBA{Float64}=ColorTypes.RGBA(0.0,0.0,0.0,1.0))

Overlay text on img in-place.

rendertext(str::String;
    height::Int=0,
    font::String="Courier",
    color::ColorTypes.RGBA{Float64}=ColorTypes.RGBA(0.0,0.0,0.0,1.0),
    backgroundColor::ColorTypes.RGBA{Float64}=ColorTypes.RGBA(0.0,0.0,0.0,0.0))

Render monospaced text from character lookup tables. Not recommended for high quality output. Loads slowly first time, or whenever the font is changed. Much faster next time.

font: "Courier", "Courier New", "Monaco"
