Default config for manim project switches pixel_height with pixel_width

[DominQu]

Description of bug / unexpected behavior

When following the quickstart guide, I created a manim project with the command: manim init project my-project --default. This created a manim.cfg file with the following contents:

[CLI]
frame_rate = 30
pixel_height = 854
pixel_width = 480
background_color = BLACK
background_opacity = 1
scene_names = Default

The values of pixel_height and pixel_width are switched. This leads to animations being zoomed in and wrong frame_width. When I set pixel_width=854 and pixel_height=480 everything goes back to normal.

Expected behavior

Default manim.cfg file contains proper resolution, that is:

[CLI]
frame_rate = 30
pixel_height = 480
pixel_width = 854
background_color = BLACK
background_opacity = 1
scene_names = Default

How to reproduce the issue

Code for reproducing the problem

manim init project my-project --default

Additionally, you can add a line: print(config.frame_width) to main.py in my-project and verify that the value of config.frame_width != 14.2(3).

I made a PR fixing the issue.

The pixel_width and pixel_height were being set out of order.

# manim/cli/init/commands.py
if key == "resolution":
     cli_config["pixel_height"] = str(value[0])
     cli_config["pixel_width"] = str(value[1])

Swapping the values fixes the issue.

# manim/cli/init/commands.py
if key == "resolution":
     cli_config["pixel_width"] = str(value[0])
     cli_config["pixel_height"] = str(value[1])
