Minimal example:
\startbuffer
\startTABLE[frame=off,align={middle,lohi}]
\NC none \NC \externalfigure[cow][ratio] \NC \NR
\NC max \NC \externalfigure[cow][ratio][factor=max] \NC \NR
\NC fit \NC \externalfigure[cow][ratio][factor=fit] \NC \NR
\stopTABLE
\stopbuffer
\starttext
\subject {Width > Height}
\defineexternalfigure[ratio][height=1cm,width=5cm]
\getbuffer
\subject {Height > Width}
\defineexternalfigure[ratio][width=1cm,height=5cm]
\getbuffer
\stoptext
See attached output.
I thought that factor=max scales the figure (while maintaining the aspect
ratio) until the used_width > asked_width and used_height > asked_height.
Looking at the grph-inc.mkiv (in particular \grph_scale_apply_size), I
no longer understand what factor=max is supposed to do!
facor=fit seems to behave as expected, although I don't understand the purpose of factor=broad (why subtract 4*bodyfont? To fit the caption?)
