"""
ConEmu (Windows) output abstraction.
ConEmu is a Windows console application, but it also supports ANSI escape
sequences. This output class is actually a proxy to both `Win32Output` and
`Vt100_Output`. It uses `Win32Output` for console sizing and scrolling, but
all cursor movements and scrolling happens through the `Vt100_Output`.
This way, we can have 256 colors in ConEmu and Cmder. Rendering will be
even a little faster as well.
