"""Create a new context with the desired pixel size.
`x`, `y`, `width`, and `height` are the desired position and size of the
window. If these are None then they will be derived from `columns` and
`rows`. So if you plan on having a console of a fixed size then you should
set `columns` and `rows` instead of the window keywords.
`columns` and `rows` is the desired size of the console. Can be left as
`None` when you're setting a context by a window size instead of a console.
Providing no size information at all is also acceptable.
`renderer` is the desired libtcod renderer to use.
Typical options are :any:`tcod.context.RENDERER_OPENGL2` for a faster
renderer or :any:`tcod.context.RENDERER_SDL2` for a reliable renderer.
`tileset` is the font/tileset for the new context to render with.
The fall-back tileset available from passing None is useful for
prototyping, but will be unreliable across platforms.
`vsync` is the Vertical Sync option for the window. The default of True
is recommended but you may want to use False for benchmarking purposes.
`sdl_window_flags` is a bit-field of SDL window flags, if None is given
then a default of :any:`tcod.context.SDL_WINDOW_RESIZABLE` is used.
There's more info on the SDL documentation:
https://wiki.libsdl.org/SDL_CreateWindow#Remarks
`title` is the desired title of the window.
`argv` these arguments are passed to libtcod and allow an end-user to make
last second changes such as forcing fullscreen or windowed mode, or
changing the libtcod renderer.
By default this will pass in `sys.argv` but you can disable this feature
by providing an empty list instead.
Certain commands such as ``-help`` will raise a SystemExit exception from
this function with the output message.
When a window size is given instead of a console size then you can use
:any:`Context.recommended_console_size` to automatically find the size of
the console which should be used.
