No.

That is what the graphic card hardware does. The software requests same 
to do graphic primitives (like draw rectangle, draw line, copy 
rectangle). As the main bottleneck is the interface between the CPU and 
the graphic card, the count of those calls should be as low as possible. 
That is why drawing single pixels always is a really bad idea.
