330               Extension in DMX, one obvious solution would be to

377                   differently, so an XCopyAreaScaled extension could be

382                   The XCopyAreaScaled extension provides new
383                   functionality that the X Video Extension does not

389                   The main drawback to this extension is that it is new
393                   Extension will be implemented for a particular piece
394                   hardware because the X Video extension has multimedia
396                   XCopyAreaScaled extension to be implemented along with
397                   the X Video extension, especially if it becomes
406                   that is using the XCopyAreaScaled extension.  However,
407                   this implementation pathway would make this extension

593               least two additional extension calls should be
618               Extension for DMX.  The window contents must be scaled,
638                 The XCopyAreaScaled extension should be implemented, since
640                 since making use of this extension will require minimal
646                 of the X protocol extension, writing this up in the
647                 usual format for extension documentation, implementation
651                 and implementation of support for this extension in DMX.
654                 We suggest implementing the extension first on the ATI
685                 should also fall back to using the X Video Extension.

708           XCreateScaledWindow extension because of the complexity
710           XPutImageScaled extension because it requires the same amount
711           of work as the XCopyAreaScaled extension, but provides less
