'''OpenGL extension NV.viewport_array2
This module customises the behaviour of the
OpenGL.raw.GLES2.NV.viewport_array2 to provide a more
Python-friendly API
Overview (from the spec)
This extension provides new support allowing a single primitive to be
broadcast to multiple viewports and/or multiple layers. A shader output
gl_ViewportMask[] is provided, allowing a single primitive to be output to
multiple viewports simultaneously. Also, a new shader option is provided
to control whether the effective viewport index is added into gl_Layer.
These capabilities allow a single primitive to be output to multiple
layers simultaneously.
The gl_ViewportMask[] output is available in vertex, tessellation
control, tessellation evaluation, and geometry shaders. gl_ViewportIndex
and gl_Layer are also made available in all these shader stages. The
actual viewport index or mask and render target layer values are taken
from the last active shader stage from this set of stages.
This extension is a superset of the GL_AMD_vertex_shader_layer and
GL_AMD_vertex_shader_viewport_index extensions, and thus those extension
strings are expected to be exported if GL_NV_viewport_array2 is
supported. This extension includes the edits for those extensions, recast
against the reorganized OpenGL 4.3 specification.
The official definition of this extension is available here:
