 Hi
 
 The attached patch adds 16bpp and 32bpp Rotation 180 Converter Code to
 evas. I did not add the 180 degrees rotation to the software_qtopia
 engine as I cannot test it at the moment.

the qtopia engine is unfortunately a 2nd tier engine - not amazingly well
supported :( so don't worry. patch in cvs. thanks! :)

 Please apply.
