The high-DPI imagelist adds a new entry to the lfm file, "BitmapAdv". Is
this really absolutely necessary in all cases, for example if the
imagelist contains only standard-resolution images? The problem is that
once a form with an image list has been opened by Laz trunk it cannot be
opened by Laz 1.8 or older any more without an error message and the
need to remove this new entry. In particular, this is an issue for
third-party components where the author must be very careful to save
demo forms with Laz 1.8, not with trunk.
I remember I had the same argument with the addition of
"Application.Scaled := true" to the lpr file, but here portability could
kept by putting it into an {$if lclversion >= 1090000} directive. In the
lfm files, however, such directives are not allowed.
