Right now, these are essentially no-ops. Later, some real mechanism needs to be used:
|
|
|
|
1) [Preferred] XRandR extension
|
|
2) XF86VideoMode extension
|
|
|
|
That will get good and messy then. In particular, if a set of headers isn't available for the platform,
|
|
then it basically won't compile. Seems like I need to re-write a few definitions in-line, and of course,
|
|
link dynamically and do proper version queries (*.so doesn't mean server actually supports it).
