'''OpenGL extension ARB.depth_buffer_float
This module customises the behaviour of the
OpenGL.raw.GL.ARB.depth_buffer_float to provide a more
Python-friendly API
Overview (from the spec)
This extension provides new texture internal formats whose depth
components are stored as 32-bit floating-point values, rather than the
normalized unsigned integers used in existing depth formats.
Floating-point depth textures support all the functionality supported for
fixed-point depth textures, including shadow mapping and rendering support
via EXT_framebuffer_object. Floating-point depth textures can store
values outside the range [0,1].
Additionally, this extension provides new packed depth/stencil pixel
formats (see EXT_packed_depth_stencil) that have 64-bit pixels consisting
of a 32-bit floating-point depth value, 8 bits of stencil, and 24 unused
bites. A packed depth/stencil texture internal format is also provided.
This extension does not provide support for WGL or GLX pixel formats with
floating-point depth buffers. The existing (but not commonly used)
WGL_EXT_depth_float extension could be used for this purpose.
The official definition of this extension is available here:
