It sets the minimal version of sdl-image1.2 that other package depend on.
So if you have another package that links against libsdl-image1.2 it will depend
on libsdl-image1.2 (>= 1.2.8).
This is necessary when the library adds new interfaces/functions at some point.
If you leave it out the dependency is versionless.

Most SDL libraries specify an INTERFACE_AGE in confiugre.in. It provides the number
of releases where no new interfaces have been added.
So MICRO_VERSION - INTERFACE_AGE is the number you need to pass to dh_makeshlibs.
For sdl-image that's 11 - 3 = 8.
