// Description:	Decode the PCX Image and store the output in UGA Format

// Input:		VOID *PCXImage - Pointer to the memory that has the PCX 
//						Image that need to be decoded.
//					UINT32 PCXImageSize - Size of the PCX Image
//					OUT VOID **UgaBlt - Two cases
//						Case 1: Memory is expected to be allocated by the callee.
//							Address provided as input should be NULL.
//							pointer that will receive the address of the UGA buffer. 
//							The buffer is allocated by callee.	
//							This buffer need to be freed by the caller. 		
//						Case 2: Memory is allocated by the caller
//					OUT UINT32 *UgaBltSize - Pointer that stores Size of UgaBlt in bytes. 
//						This will be treated as an input. This should have value ZERO for Case 2 above.
//					UINT32 *PixelHeight - Height of UgaBlt/PCX Image in pixels
//					UINT32 *PixelWidth - Width of UgaBlt/PCX Image in pixels
