GXPD 07 - Inconsistencies, LaserWriter 'xdtl', adding a padByte (1-May-95)

Q I see that you have addressed the inconsistency between the declaration of the flipping collections and their use in the LaserWriter's xdtl stuff by adding a padByte. However, there are a few other single-Boolean collection types which don't have padBytes (e.g., gxInvertPageInfo). Shouldn't these have padBytes also to avoid future problems?

A We went through the interface files and took a close look at all of the single-Boolean collection types. We only added the padBytes to items which seemed to require it. If single-Boolean collection types were working without any problems, we left them alone (i.e., didn't add the padBytes). The invert item was fixed in GX v1.1. f1c1. Other Boolean items are not currently an issue, because the LaserWriter GX driver doesn't use them. We're trying to keep the interface files as "pure" as possible.
