Title: Let Ghostscript generate one JPEG per page 

Multipart questions can span multiple pages. And therefore, when
showing the individual question, one needs to be able to show one
JPEG per page

Ghostscript can do that for you by generating one JPEG per PDF page.
The same change should also be made in answer-key.mk. There is no
need - as is being done now - to generate separate TeX files per page
just to create JPEGs of individual pages. Simply create the composite PDF
first and then let Ghostscript do the rest

I know. Its silly that I took so long to discover the requisite ghostscript option
