* Project Name : Westwood 32 Bit Library *
* *
* File Name : GBUFFER.H *

***************************************************************************
* *
* This module contains the definition for the graphic buffer class. The *
* primary functionality of the graphic buffer class is handled by inline *
* functions that make a call through function pointers to the correct *
* routine. This has two benefits: *
* *
* *
* 1) C++ name mangling is not a big deal since the function pointers *
* point to functions in standard C format. *
* 2) The function pointers can be changed when we set a different *
* graphic mode. This allows us to have both supervga and mcga *
* routines present in memory at once. *
* *
* In the basic library, these functions point to stub routines which just *
* return. This makes a product that just uses a graphic buffer take the *
* minimum amount of code space. For programs that require MCGA or VESA *
* support, all that is necessary to do is link either the MCGA or VESA *
* specific libraries in, previous to WWLIB32. The linker will then *
* overide the the necessary stub functions automatically. *
* *
* In addition, there are helpful inline function calls for parameter *
* ellimination. This header file gives the defintion for all *
* GraphicViewPort and GraphicBuffer classes. *
* *
* Terminology: *
* *
* Buffer Class - A class which consists of a pointer to an allocated *
* buffer and the size of the buffer that was allocated. *
* *
* Graphic ViewPort - The Graphic ViewPort defines a window into a *
* Graphic Buffer. This means that although a Graphic Buffer *
* represents linear memory, this may not be true with a Graphic *
* Viewport. All low level functions that act directly on a graphic *
* viewport are included within this class. This includes but is not *
* limited to most of the functions which can act on a Video Viewport *
* Video Buffer. *
* *
* Graphic Buffer - A Graphic Buffer is an instance of an allocated buffer *
* used to represent a rectangular region of graphics memory. *
* The HidBuff and BackBuff are excellent examples of a Graphic Buffer. *
* *
* Below is a tree which shows the relationship of the VideoBuffer and *
* Buffer classes to the GraphicBuffer class: *
* *
* BUFFER.H GBUFFER.H BUFFER.H VBUFFER.H *
* ---------- ---------- ---------- ---------- *
* | Buffer | | Graphic | | Buffer | | Video | *
* | Class | | ViewPort | | Class | | ViewPort | *

* GBUFFER.H VBUFFER.H *
*-------------------------------------------------------------------------*
* Functions: *
* GBC::GraphicBufferClass -- inline constructor for GraphicBufferClass *
* GVPC::Remap -- Short form to remap an entire graphic view port *
* GVPC::Get_XPos -- Returns x offset for a graphic viewport class *
* GVPC::Get_Ypos -- Return y offset in a GraphicViewPortClass *
* VVPC::Get_XPos -- Get the x pos of the VP on the Video *
* VVPC::Get_YPos -- Get the y pos of the VP on the video *
* GBC::Get_Graphic_Buffer -- Get the graphic buffer of the VP. *
* GVPC::Draw_Line -- Stub function to draw line in Graphic Viewport Class*
* GVPC::Fill_Rect -- Stub function to fill rectangle in a GVPC *
* GVPC::Remap -- Stub function to remap a GVPC *
* GVPC::Print -- stub func to print a text string *
