Investigate fixing the titlebar text area

[Lootyhoof]

Currently the titlebar text is rendered a bit strangely.

• If left unstyled (i.e. styled by the browser) it's drawn quite a ways above the window frame
• With the current titlebar implementation (drawing a gradient in the titlebar), this covers the text when on Aero Glass, meaning that there is no visible titlebar text in this instance
• The current fix to make the text visible (moving the text down) causes overflow issues into the client area with long strings; especially visible on smaller, non-maximized windows

Keeping this issue here so I can continue to look into this mess.
