Convert all coordinates within the visual tools to Vector2D, which has been significantly extended. Eliminates a lot of issues with accumulated rounding errors and simplifies a lot of code. Modernize the visual tools' interactions with the rest of Aegisub by connecting to signals directly rather than routing everything through the video display and converting the main visual tool mode toolbar to the command system. Extract all references to OpenGL from the visual tools and move them to OpenGLWrapper as a first step towards making it possible to implement an alternative video renderer. In the process, eliminate all uses of OpenGL immediate mode. Fix a bunch of minor issues and general instability. Originally committed to SVN as r5823.
