           Summary: TreeView HitTest is inaccurate with owner drawn
                    checkboxes
           Product: Mono: Class Libraries
           Version: 1.2.6
          Platform: PC
        OS/Version: Windows XP
            Status: NEW

Description:
TreeView HitTest is inaccurate with owner drawn checkboxes

To reproduct:
1. Create a TreeView
2. Set CheckBoxes = false
3. Create an ImageList with 2 images
4. Set TreeView.StateImageList to the ImageList created above
5. Create some nodes and set the StateImageIndex to 0 for each of them
6. Run
7. Click on a checkbox.

(NOTE: see bug 363353 if the above setup causes an exception in Mono.)

Actual results:
The tree is expanded and collapsed after clicks on the checkbox rather than
clicks on the plus/minus. Click on the plus/minus does nothing.

Expected results:
Clicking the checkbox should do nothing since, in this example, no code has
been written to respond to it. Clicking on plus/minus should expand/collapse
the tree.

In code:
  TreeView.HitTest has:
        else if (checkboxes && IsCheckboxArea (n, x))
                return new TreeViewHitTestInfo (n,
TreeViewHitTestLocations.StateImage);

    But that does not consider user-drawn check boxes when TreeView.checkboxes
= false
