This fixes two bugs in SetScrollRange:
- Setting the scroll range with the "bRedraw" flag set to true on a
non-control scrollbar results in the scrollbar being drawn over the whole window area.
- If you don't set WS_HSCROLL/WS_VSCROLL on window creation, setting a scroll
range does nothing. Setting the scroll range to a non-zero range should cause scroll bars to be displayed (and the appropriate flag to be set in the window styles). Setting the range to a zero range should cause the relevant scroll bar to be hidden (and the flag to be removed from the window styles).
The second attachment is a test program that can be used to verify the behaviour associated with the second bug by using the left and right mouse buttons to set a non-zero/zero scroll range on mouse-down/mouse-up. The left mouse button affects SB_HORZ and the right affects SB_VERT.
Thanks Troy for fixing a breakage I introduced with my recent patch. This patch certainly can be applied, after that I'll send a more comprehensive test suite and a few more fixes I have in my tree.
