 Summary:

 There is a problem in the Autodesk windows client when using the code path
 to get the rules filter for the current layer based on the current map
 scale.  The problem is that the rules filter that is built does not
 account for the "default" rule which matches all features.  So now certain
 commands are filtering out some features because they don't match any of
 the other rules, but they do match the default rule.

 The fix is to modify the method DefaultStylizer::!GetRulesFilter so that
 it iterates backward (since default rule is at the end usually) and bail
 out returning NULL if it finds a default rule.

 Solution details:

 \\!MgDevBranch\2.5Knight\OS\Common\Stylization\!DefaultStylizer.cpp

 Reverse order of iteration so that we can find the default rule faster.
 Usually it is at the end of the collection.

 If we see the default rule in any of the rules, return NULL from
 !GetRulesFilter.  The default rule will match all features, so we don't
 need to return a rule filter if we encounter a default rule.

 Components Affected:

 !MgStylization.dll
