gimp/plug-ins/xjt/xpdb_calls.c
Sven Neumann 6b56a53703 tools/pdbgen/pdb/guides.pdb fixed a bug in image_find_next_guide 
* tools/pdbgen/pdb/guides.pdb
        * app/guides_cmds.c: fixed a bug in image_find_next_guide

        * plug-ins/xjt: reflect the name change of gimp_image_find_next_guide

        * app/interface.c: applied the patch from
        Shuji Narazaki <narazaki@gimp.org> that allows to open images by
        dropping them onto the toolbar

/* xpdb_calls.c
*
* this module contains calls of procedures in the GIMPs Procedural Database
* IMPORTANT Note:
* some of these procedures are not available in the official GIMP 1.0.2 releases
* (and prior releases)
*
* The missing procedures (except guides) are available as patches to the gimp core.
* If you dont install the patches XJT will work, but some Informations
* can not be saved or loaded.
* - floating selections
* - the layers linked state
* - guides
*
* GIMP 1.1 will provide all the procedures to run XJT at full fuctionality.
* There are no Patches required to run XJT in the latest GIMP 1.1
* development version
