Increase the default project window size for better usability

[Calinou]

The new default window size is tuned to:

• Have a 16:9 aspect ratio,
• Have both dimensions divisible by 8 to better play along with video recording,
• Be displayable correctly in windowed mode on a 1366×768 display (tested on Windows 10 with default settings).

This breaks compatibility with projects that didn't change the window size from the default value (or that kept one of the values to its default).

On the list of 16:9 resolutions that divide by 8, 1152×648 is a middle ground between 1024×576 and 1280×720. 1024×576 would have been even smaller than the current default, but it would have been 16:9 unlike the current default resolution which has a ~1.706 aspect ratio. In contrast, 1280×720 is too large to work everywhere (see below).

Why not 1280×720?

On a 1366×768 monitor (still common in budget laptops today), a 1280×720 window can't be displayed correctly in windowed mode when using the default Windows 10 configuration:

In contrast, a 1152×648 window fits well.

i think a predefined list of resolutions and aspect ratios could also be very handy to select from

For pixel art games, picking a base resolution is a very case-by-case scenario. Some people will want to use the same resolutions as old consoles, but their resolutions can be looked up online with relative ease. I'm not sure if having a list of presets would bring a noticeable usability benefit, not to mention this would add a second way to set the same setting (which introduces choice paralysis).

For non-pixel art games, there are fewer sensible base resolutions to choose from, but it's still not something that would work well given the current project settings dialog.

Approved in the Editor team meeting. Needs a rebase.

This change can negatively affect people with small displays/laptops, so we should listen to the feedback we get from the following alphas and revert it if the change is overwhelmingly negative.

Thanks!
