/**
* Native bindings to the OES_viewport_array extension.
*
* OpenGL ES is modeled on a pipeline of operations. The final stage in this pipeline before rasterization is the viewport transformation. This stage
* transforms vertices from view space into window coordinates and allows the application to specify a rectangular region of screen space into which
* OpenGL ES should draw primitives. Unextended OpenGL ES implementations provide a single viewport per context. In order to draw primitives into multiple
* viewports, the OpenGL ES viewport may be changed between several draw calls. With the advent of Geometry Shaders, it has become possible for an
* application to amplify geometry and produce multiple output primitives for each primitive input to the Geometry Shader. It is possible to direct these
* primitives to render into a selected render target. However, all render targets share the same, global OpenGL ES viewport.
*
* This extension enhances OpenGL ES by providing a mechanism to expose multiple viewports. Each viewport is specified as a rectangle. The destination
* viewport may be selected per-primitive by the geometry shader. This allows the Geometry Shader to produce different versions of primitives destined for
* separate viewport rectangles on the same surface. Additionally, when combined with multiple framebuffer attachments, it allows a different viewport
* rectangle to be selected for each. This extension also exposes a separate scissor rectangle for each viewport. Finally, the viewport bounds are now
* floating point quantities allowing fractional pixel offsets to be applied during the viewport transform.
*
* Requires {@link GLES32 GLES32}, {@link EXTGeometryShader EXT_geometry_shader} or {@link OESGeometryShader OES_geometry_shader}.
