API Change Proposal - Re: MSAA and Scene anti aliasing

D'oh!  I knew I should have been checking this list a bit.  I hope this isn't too late to have any impact...

As an intermediate solution this is fine, but when we want to get into providing settings for MSAA and FSAA and other algorithms I think classes are more flexible than enums.  How about this solution:

package javafx.?

public class SceneAntialiasing {
     public static final SceneAntialiasing DISABLED;
     public static final SceneAntialiasing BALANCED;
     public static final SceneAntialiasing FASTEST;
     public static final SceneAntialiasing NICEST;

     public static SceneAntialiasing[] getAvailableTechniques() { }

     SceneAntialiasing() { /* package private constructor! */ }
}

public class MsaaAntialiasing extends SceneAntialiasing {
     MSaaAntialiasing(int numsamp) { /* package private */ }
     public int getNumSamples();
}

public class FsaaAntialiasing extends SceneAntialiasing {
     FsaaAntialiasing(int numsamp) { /* package private */ }
     public int getNumSamples();
}

Note that there are ways for the system to construct these objects without providing public constructors so that these become statically defined by the system.

What about Anisotropic filtering?  Is that considered a form of AA, or an option on top of AA?

After listening to the feedback and an internal discussion, we would like to propose a minor change to the API for supporting scene anti-aliasing. We intentionally choose not to expose the number of samples and techniques used in this release, but this doesn't preclude future addition when the time is right for more options. This change will be tracked by RT-31878 (https://javafx-jira.kenai.com/browse/RT-31878):
