TITLE : Chapter 8 - OpenGL Programming Guide
* glCopyPixels() - Copies a rectangular array of pixels from one part of the framebuffer to another. This command behaves similarly to a call to glReadPixels() followed by a call to glDrawPixels(), but the data is never written into processor memory........

TITLE : Chapter 8 - OpenGL Programming Guide
The basic ideas in Figure 8-3 are correct. The coordinates of glRasterPos*(), which specify the current raster position used by glDrawPixels() and glCopyPixels(), are transformed by the geometric processing pipeline. Both glDrawPixels() and glCopyPixels() are affected by rasterization and per-fragment operations. (But when drawing or copying a pixel rectangle, there's almost never a reason to have fog or texture enabled.).......

TITLE : Chapter 8 - OpenGL Programming Guide
Copies pixel data from the framebuffer rectangle whose lower-left corner is at (x, y) and whose dimensions are width and height. The data is copied to a new position whose lower-left corner is given by the current raster position. buffer is either GL_COLOR, GL_STENCIL, or GL_DEPTH, specifying the framebuffer that is used. glCopyPixels() behaves similarly to a glReadPixels() followed by a glDrawPixels(), with the following translation for the buffer to format parameter:.......

TITLE : Chapter 8 - OpenGL Programming Guide
Note that there's no need for a format or data parameter for glCopyPixels(), since the data is never copied into processor memory. The read source buffer and the destination buffer of glCopyPixels() are specified by glReadBuffer() and glDrawBuffer() respectively. Both glDrawPixels() and glCopyPixels() are used in Example 8-4........

TITLE : Chapter 8 - OpenGL Programming Guide
glCopyPixels() applies all the pixel-transfer operations during what would be the glReadPixels() activity. The resulting data is written as it would be by glDrawPixels(), but the transformations aren't applied a second time. Figure 8-5 shows how glCopyPixels() moves pixel data, starting from the frame buffer........

TITLE : Chapter 8 - OpenGL Programming Guide
Sets the magnification or reduction factors for pixel-write operations (glDrawPixels() or glCopyPixels()), in the x- and y-dimensions. By default, zoomx and zoomy are 1.0. If they're both 2.0, each image pixel is drawn to 4 screen pixels. Note that fractional magnification or reduction factors are allowed, as are negative factors. Negative zoom factors reflect the resulting image about the current raster position........

If my adaptation of OpenGL could be integrated this closely with the existing VDU graphics system then I could dispense with many of the more mundane GL commands, such as those controlling the framebuffers and basic pixel area manipulation operations (e.g. glDrawBuffer(), glReadPixels(), glCopyPixels() and glDrawPixels())........
