class TGopBitBlt : public TGraphicsOperation;
An accelerated graphics operation that copies a rectangular region of one bitmap into another.
The data members are all initialised on construction. Objects of this class can be passed to a graphics accelerator's Operation() function either individually, or in a buffer.
