Ok, I just wanted to know if I had to update wx for the windows builds.

> Antialiasing is not dependent on wx.  wx doesn't actually need to support or not support it.  The bug in question is that wx doesn't really ask the driver if multisampling (antialiasing) is supported the way windows wants, so it incorrectly repots that it doesn't work.

Many drivers (at least windows one, such as if you install Catalyst Control Center in windows for example) allow you to override applications that ask for a nonmultisampled context.  Basically, wx takes what the driver gives it (as does everything else) so if the context is multisampled, it is multisampled.  It's not something wx really has the option of supporting or not supporting.  In this case, only the check to see if it is supported is broken.

Honestly, just letting the driver give the context it gives is a perfectly valid solution.  Often, there will only be code that is there specifically to turn MSAA off (for performance, if needed) but it won't ever be explicitly turned on.
