| '''OpenGL extension OES.surfaceless_context |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GLES2.OES.surfaceless_context to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| Applications that only want to render to framebuffer objects should |
| not need to create a throw-away EGL surface (typically a 1x1 |
| pbuffer) just to get a current context. The EGL extension |
| KHR_surfaceless_context provides a mechanism for making a context |
| current without a surface. This extensions specifies the behaviour |
| of OpenGL ES 1.x and OpenGL ES 2.0 when such a context is made |
| current. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/OES/surfaceless_context.txt |
