       We use libtool CURRENT:REVISION:AGE versioning scheme. Here are the
       rules for updating the values below, this should be done whenever wx
       version (wx/version.h) changes (we abbreviate WX_CURRENT:REVISION:AGE
       as C:R:A respectively):

       0. Set C:R:A = 0:0:0 if major or minor version has changed.

       1. If any API has been removed or otherwise changed in backwards
          incompatible way, then change C:R:A to C+1:0:0

       2. Else, if any API has been added, change C:R:A to C+1:0:A+1

       3. Else, i.e. if there were no changes at all to API but only internal
          changes, change C:R:A to C:R+1:A
