| '''OpenGL extension NV.framebuffer_blit |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GLES2.NV.framebuffer_blit to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension modifies OpenGL ES 2.0 by splitting the |
| framebuffer object binding point into separate DRAW and READ |
| bindings. This allows copying directly from one framebuffer to |
| another. In addition, a new high performance blit function is |
| added to facilitate these blits and perform some data conversion |
| where allowed. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/NV/framebuffer_blit.txt |
