- Remove unused hVScrollBar and hHScrollBar members in GUI_CONSOLE_DATA.

- Remove ScreenBufferSize member from GUI_CONSOLE_DATA; when building the structure for console.dll, send the actual screen buffer size instead.
- GuiConsolePaint, GuiIntDrawRegion: Adjust coordinates based on buffer's scroll position.
- GuiConsolePaint: Use ConioCoordToPointer when finding attribute at top-left.
- GuiConsoleHandlePaint: Don't leak the DC when the paint rectangle is empty.
- GuiConsoleHandleScroll: Actually update the buffer's scroll position, not just the scrollbar's. Allow scrolling either horizontally or vertically. Fix typo in SB_THUMBTRACK case. Don't rely on GetScrollInfo for bound checking - any thread can sabotage the scrollbar ranges.
- CsrGetScreenBufferInfo: Return the visible area in srWindow.
