As for cropping, the DrRacket REPL is the thing that does the cropping
(and, in some cases, it may not be cropping, actually, but two
different parts of the window are fighting with each other for the
pixels when something draws outside of its bounding box, as a scaled
hline does).
Okay, I thought there was a guarantee that the drawing happened
inside the bounding box.
That is not a guarantee and importantly not one (for picts, generally
speaking, that is). refocus is a common way that guarantee fails to
hold, for example.
It really should be guaranteed by the REPL, though. This is awful:
#lang racket
(require slideshow)
(dc (λ (dc x y)
(send dc set-background "magenta")
(send dc clear))
100 100)
Shouldn't snips generally not be allowed to draw outside their bounding
boxes?
