I think this is a good idea. I would suggest gles[123] and |
| 27 |
gles[123]-only to avoid some of the churn. Changing gles[123] to |
| 28 |
gles[123]-support would mean changing a ton of reverse dependencies of |
| 29 |
Mesa, and I think that's a bad idea. |

Making a pull request to change these seems like a great plan. I'll be |
| 54 |
happy to help or review. |
