[sane-devel] [RFC] how to enable 1.1 features

[Alessandro Zummo]

 Hi folks,

  please see the attached patch regarding my proposal
 for a safe enabling of 1.1 features in the backends.

  I've included a few small docs, checked some drivers
 for the correct behaviour and added 1.1 features
 to the coolscan3 driver.

 The basic points of my proposal are:

 a) no modifications required for current frontends

 b) safe enabling, only an 1.1 fronted can activate 1.1 features

 c) I will check every driver in the tree for correct behaviour
 before the 1.1 release.



 before you ask, I know there are out of tree backends. Those backends
 can either:

 a) keep linking against 1.0 tree

 b) compile against 1.1 and check that they handle unknown enums
 in sane_control_option
