| '''OpenGL extension EXT.debug_label |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GLES2.EXT.debug_label to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension defines a mechanism for OpenGL and OpenGL ES applications to |
| label their objects (textures, buffers, shaders, etc.) with a descriptive |
| string. |
| |
| When profiling or debugging such an application within a debugger or |
| profiler it is difficult to identify resources from their object names. |
| Even when the resource itself is viewed it can be problematic to |
| differentiate between similar resources. Attaching a label to an object |
| helps obviate this difficulty. |
| |
| The intended purpose of this is purely to improve the user experience |
| within OpenGL and OpenGL ES development tools. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/EXT/debug_label.txt |
