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.
