Bug 158304

Example draw file with two shapes

Draw has a Cross-fading feature for shapes. This has some settings in its dialog, but these are not saved / loaded properly between different runs of Draw, despite the code making efforts to save them.

1. Open the attached Draw file, it has two drawing shapes.
2. Select both by clicking and pressing Shift
3. Go to Shape - Cross-fading menu.
4. Try to change the settings, change the Increments value, uncheck the boxes. 5. Press OK. The cross-fading is executed fine.
6. Close LO without saving the document, then reload.
7. Do steps 2-3.
-> The settings you changed are reset to the default values.

Code pointers:
sd/source/ui/dlg/morphdlg.cxx
This tries to load/save settings as a SotStorageStream object, this is an obsolete approach
officecfg/registry/schema/org/openoffice/Office/Draw.xcs
-> CrossFading group of settings

(I found this issue because my bin/find-unused-configkeys.sh script reported this group as unused.)
