demo 08_geometry.cr finish with error

[unplugandplay]

My env:
Crystal 1.3.2 (2022-01-18)

LLVM: 13.0.0
Default target: aarch64-apple-darwin21.1.0

running 08_geometry.cr

I end up with the following error:

In lib/sdl/src/rect.cr:26:20

 26 | def initialize(@x, @y, @w, @h)
                     ^-
Error: instance variable '@x' of SDL::Rect must be Int32, not Float64

I have to change
renderer.fill_rect(width / 4, height / 4, width / 2, height / 2)
to
renderer.fill_rect((width / 4).to_i, (height / 4).to_i, (width / 2).to_i, (height / 2).to_i)
to have it working.

Or replace / (float dividion) with // (integer division).
