In this case \int and \sum are of the same size, so it appears as a
design choice, and more importantly, we can patch the font to change
DisplayOperatorMinHeight.
It's really weird ... in the virtual font builder we have
DisplayOperatorMinHeight = t . math_operator_size . text_style
and there has been a good reason for this otherwise it would not be
there. For the normal (12pt) size this becomes 1040448 for px as well as
tx. Both fonts (when looking at them with \showfont[pxex.tfm] etc have
the same shapes.
Concerning the rest of the parameters, only for this case irrelevant
differ a bit.

So, there is no real reason for px to behave different than tx. However,
when we nil DisplayOperatorMinHeight we get the scaled glyph. Okay, we
could have threshold issue but even putting some real large math mess
after itm it will not bump to the next size shape (there is only one
larger size btw) .. puzzling
BTW, what is the status of Pagella Math? Should we default to that
instead of px-fonts?
not yet
