| 38 | * Among the features of this module are: |
| 39 | * <UL> |
| 40 | * <LI> Structures to represent most GL state </LI> |
| 41 | * <LI> State set/get functions </LI> |
| 42 | * <LI> Display lists </LI> |
| 43 | * <LI> Texture unit, object and image handling </LI> |
| 44 | * <LI> Matrix and attribute stacks </LI> |

Brian Paul | 253204f | 2004-09-10 00:45:12 +0000 | [diff] [blame] | 47 | * Other modules are responsible for API dispatch, vertex transformation, |
| 48 | * point/line/triangle setup, rasterization, vertex array caching, |
| 49 | * vertex/fragment programs/shaders, etc. |
