Hmm, well bumpmapping is for bevels (shading). To a certain extent you can make the bulging without any shading.
If you think of the bulging coming from text being reflected in a convex mirror, it would get distorted and blown up (thats where, theoretically speaking, a displacement map would come into play).

So i think the letter 'I', displayed as a rectangle would look like this:
And i think the Lens Distortion filter in Gimp realized that quite well, after i made the perspective distorted letters in Inkscape.
My shading isnt very accurate. But it fools you to a certain extent, that it maybe is
This tutorial is a very good example what you can do with a displacment map
