Like I mentioned before, fpGUI doesn't use the built-in streaming
features of the RTL. fpGUI's property editors each know how to read or
write it's data. fpGUI handles images differently, so there is no need
for a Image1.Data property. In fpGUI you register images with framework,
then simply reference those images by name. This also has the benefit
that it reuses images (reducing the memory footprint).

fpGUI doesn't have such properties, so those would fall under the
"unknown lines" memo and simply get ignored by the UI designer. Then
when you compile your project, any forward declaration will have to be
added in code.
