<div dir="ltr">Oh, and another thought: it appears that the 2htdp/image documentation just went from 4 megs to 15 megs (of space on the disk) with the change to SVG. It looks like there are just two images that account for nearly 10 megs, tho. So I could switch just those back to being pngs and that would make a big difference in the size. So maybe we also need finer-grained support to override the defaults in a few places?<div>

</div>I was puzzled at first, but if I understand correctly, the HtDP images<br>
aren't picts but image-snips.<br>
<br>
This implies that they don't get converted at line 585 in [1]<br>
pict-lib/texpict/private/mrpict-extra.rkt,<br>
but that the conversion called is the one in [2]<br>
gui-lib/mrlib/image-core.rkt at line 232.<br>
I only made changes in the first one, not the second one.<br>
<br>
I am unsure how to fix this - have the image snips still the pict, or<br>
have they become<br>
become bitmaps at this point?<br>
