Fix treeview with checkboxes creation

[Maxime Bellengé]

According to MSDN, it is said that CreateCompatibleBitmap should be used
whenever a color bitmap is created. 
Moreover, with CreateBitmap, I have to know the depth of the screen
whereas with CreateCompatibleBitmap I don't need to.

Dmitry (or others), do you really think this patch can't be applied as
is. I will add some comments as suggested by Marcelo Duarte.
