[AD] float color value unset

[Milan Mimica <milan.mimica1@xxxxxxxxxx>]

Value of dinfo->float_color is unset at score.c:420 and it's likely to produce undefined behavior. The same is for 
dinfo->float_depth at score.c:433. It happens only if these two values are not set explicitly through allegro_gl_set(). 
Take a look at backtrace for more info.
