* app/Makefile.am
* app/gimpdrawable-preview.[ch]: new files formerly known as
gimpdrawablepreview.[ch].
This is a new naming scheme for methods of objects which live
outside their object's file. The old name implied a derived object
(and is in fact now taken by a GimpPreview subclass, see below).
Further candidates for renaming are e.g. gimpdrawable-invert.[ch],
gimpimage-convert.[ch] etc. Finaly, the main objects (image,
drawable) will go to their own directories together with their
subclasses.
* app/apptypes.h: added typedefs for the new objects:
* app/gimpbrushpreview.[ch]
* app/gimppatternpreview.[ch]: new subclasses of GimpPreview.
* app/gimpdrawablepreview.[ch]: contains a subclass of GimpPreview
now.
* app/gimpviewable.[ch]: renamed the virtual functions to
"get_preview" and "get_new_preview" to avoid confusion with the
new GimpPreview subclasses.
* app/gimppreview.[ch]: virtualized "create_preview" and
"create_popup".
* app/gimpmarshal.[ch]: new marsaller for GimpPreview.
