Attachment: nsNativeThemeWin::StandardGetState was checking for focused and returning early before checking for hover

When a button is focused, and mouse hovers over, it will now show the hovered state and focus rect.  

Please let me know if there should be a test case defined for this, and if so any hints of similar bugs with similar tests would be appreciated.

I ran this patch through the following automated and there were no fails, but it ran very quickly, please let me know if there are other tests I should be running as well.  
I ran:
TEST_PATH=widget/tests/ make -C $(OBJDIR) mochitest-plain

This will apply to a number of ui elements, not just buttons. Are you sure this is the appropriate default behavior for everything this applies to?

Upon further inspection, fix looks good and also fixes another problem (see NS_THEME_TAB).
I mention below the before and after effect for all of the widget types that use the modified function:

When focused and the pointer is on top:

NS_THEME_BUTTON
- Before shows focus outline but no highlight color for mouse pointer (original reported problem)
- After Shows both focus outline and highlight color

NS_THEME_CHECKBOX
NS_THEME_RADIO
- Before shows focus outline and highlight color when pointer goes over
- After works same

NS_THEME_TEXTFIELD
NS_THEME_TEXTFIELD_MULTILINE
- Before shows slight border change with pointer on top, slightly darker change with focus
- After works same 

NS_THEME_SPINNER_UP_BUTTON
NS_THEME_SPINNER_DOWN_BUTTON
- Cannot focus, gets highlight color (no focus even with -moz-user-focus: normal;)
- After works same

NS_THEME_TAB
- Before shows focus only on the selected tab, other tabs show highlight color as mouse pointer goes over. 
  If I force focus on non active tabs with tab { -moz-user-focus: normal } though it has the same bug as the original reported bug for button
- After shows same if no explicit focus is specified.  If -moz-user-focus:normal on non active tabs, fixes problem as with NS_THEME_BUTTON

NS_THEME_TREEVIEW_HEADER_CELL
- Before does not get focus, does get highlight color
  -moz-user-focus:normal has no effect
- After works same

On a side note, should the spinner not being able to be focused with "-moz-user-focus: normal;" be posted?  Please advise and I can attempt to post if it is not already posted.

Thanks for the detailed write up! I tested each of these and compared them to IE, everything looks ok.

I think the rule on this new flag is to just set checkin? w/o an email. People who land stuff will come around and find it. Note this bug should remain open until the patch merges to mc.
