 Specifies the bitmap with the images used for the checks of the component-selection page treeview.
 
 This bitmap should have a size of 96x16 pixels and contain six 16x16 images for the different states (in order: selection mask, not checked, checked, greyed out, unchecked & read-only, checked & read-only). Use magenta as mask color (this area will be transparent).
