| 5 | * This file contains helpers which call back into the X server. The longer-
|
|---|
| 6 | * term idea is to eliminate X server version dependencies in as many files as
|
|---|
| 7 | * possible inside the driver code. Ideally most files should not directly
|
|---|
| 8 | * depend on X server symbols at all.
