Abstract
A system aids composited graphics rendering. A script and corresponding virtual machine engine code may be stored in memory. An off-screen buffer is generated in the memory by the script. The off-screen buffer includes an extended stage having first a buffer portion. The buffer portion may include pre-rendered graphical object. An on-screen buffer may include a composition of the pre-rendered graphical objects of the extended stage. The script renders a graphical change to the on-screen buffer using independent block copying, from the extended stage to corresponding target areas in the on-screen buffer, of one or more of the pre-rendered graphics of the extended stage area affected by the graphical changes.
