75     viewports, the OpenGL viewport may be changed between several draw calls.
83     viewports. Each viewport is specified as a rectangle. The destination
164     rendering to one of several viewports and is discussed in the section
176     different viewports.
206     Multiple viewports are available and are numbered zero through the
229     viewports simultaneously. <first> specifies the index of the first
230     viewport to modify and <count> specifies the number of viewports. If
243     DepthRange sets the depth range for all viewports to the same values
261     ViewportArrayv specifies parameters for multiple viewports
263     modify and <count> specifies the number of viewports. If (<first> +
286     Viewport sets the parameters for all viewports to the same values
365     The scissor test is enabled or disabled for all viewports using
384     to do its rendering for all viewports. If the default framebuffer is
387     Initially, the scissor test is disabled for all viewports.
402     Scissor sets the scissor rectangle for all viewports to the same

646        It therefore defines all viewports in a single call. This is also true
737 Fractional viewports make things more complicated, particularly if the
743 assumes that a guardband implementation with fractional viewports extends its
748 fractional viewports to be undefined.  If implementations want defined
749 behavior with fractional viewports, they can program a slightly wider viewport
761 of fractional viewports on the newly permitted scissoring.
