'''OpenGL extension EXT.multiview_draw_buffers
This module customises the behaviour of the
OpenGL.raw.GLES2.EXT.multiview_draw_buffers to provide a more
Python-friendly API
Overview (from the spec)
This extension allows selecting among draw buffers as the
rendering target. This may be among multiple primary buffers
pertaining to platform-specific stereoscopic or multiview displays
or among offscreen framebuffer object color attachments.
To remove any artificial limitations imposed on the number of
possible buffers, draw buffers are identified not as individual
enums, but as pairs of values consisting of an enum representing
buffer locations such as COLOR_ATTACHMENT_EXT or MULTIVIEW_EXT,
and an integer representing an identifying index of buffers of this
location. These (location, index) pairs are used to specify draw
buffer targets using a new DrawBuffersIndexedEXT call.
Rendering to buffers of location MULTIVIEW_EXT associated with the
context allows rendering to multiview buffers created by EGL using
EGL_EXT_multiview_window for stereoscopic displays.
Rendering to COLOR_ATTACHMENT_EXT buffers allows implementations to
increase the number of potential color attachments indefinitely to
renderbuffers and textures.
This extension allows the traditional quad buffer stereoscopic
rendering method that has proven effective by indicating a left or
right draw buffer and rendering to each accordingly, but is also
dynamic enough to handle an arbitrary number of color buffer targets
all using the same shader. This grants the user maximum flexibility
as well as a familiar interface.
The official definition of this extension is available here:
