+   vdeImb_t defines the structure of a single image buffer which is capable
+   of storing one YUV 4:2:0 image and a number of paramaters as 
+   side-information. The YUV image as well as the YUV to RGB conversion and
+   displaying related parameters are kept in a renDrawItem_t structure.
+   Decoder related parameters are stored in the vdeImb_t itself.
+   One may directly refer to the member variables of the vdeImb_t structure.
+   However, one should use the functions and macros in the Renderer Draw Item
+   Interface for accessing the contents of the drawItem member of vdeImb_t.
