cdata it is. Thanks to people like you, Racket does what I need, as usual. The
problem is I don’t always know what I need.

svg images have a second-class status in Racket. If you want to use an svg
image in a drawing, it seems that you have to use the RSVG package to load it
from a file, which then renders it to a bitmap, subject to pixelation if
scaled. How hard would it be to create an svg-pict primitive that yo

slideshow advertises that it’s configured for a display size of 1024x768. If I
want 1080p (1920x1080), is it as simple as changing 1024/768 in a couple of
files to 1920/1080 and recompiling?
What’s the proper way to do this? Is there a reason screen-w and screen-h are
not parameters?
