On the Allegro mailing list I got this well-written comparison
by Michael Bukin:

66
GRX is a multiplatform graphics library.  Also it
has support for mouse and keyboard input.  It supports drawing in
different modes (copy, or, and, xor), drawing dashed lines, pattern
filled primitives and drawing in user coordinates.  GRX supports
loadable bit-mapped fonts and can output them in different directions
and with different magnification (independent for width and height).

Allegro is also multiplatform, has graphics, mouse and keyboard input,
plus it has sound support, packfiles and fixed point math.  Allegro
can draw in different modes too, with custom blenders it can draw in
any imaginable mode.  It has no support for dashed lines (can be
partially implemented with doline) and has no drawing in user
coordinates.  Allegro can draw fonts only in one direction, but it has
hooks for rendering fonts, they can be used for drawing antialiased
and magnified fonts.  WIP version of Allegro was designed to be
portable to different platforms.
