feat: high-res screenshot

[dvdkouril]

This PR adds capability to take higher resolution screenshots.

Previously the users were expected to simply make the canvas as large as possible for larger screenshots. This is obviously limited by the physical size of their display. The new feature uses an OffscreenCanvas to render the scene at an arbitrary size.

The canvas background is kept transparent, making it easier to manipulate the images in post-production.

Usage:

// Use canvas dimensions
await renderer.screenshot();

// Specify width, calculate height from canvas aspect
await renderer.screenshot({ width: 1920 });

// Specify height, calculate width from canvas aspect
await renderer.screenshot({ height: 1080 });

// Exact dimensions (may change aspect ratio)
await renderer.screenshot({ width: 1920, height: 1080 });

// Any of the above with quality multiplier
await renderer.screenshot({ width: 4000, quality: 2 });

TODOs:

• aspect ratio of the actual canvas is not respected, leads to deformation when users don't specify width/height with the same ratio
• quality param > 1: the SSAO visuals change significantly

By deleting the fixed version specifier, the setup script will look at what version is declared as dependency in the project
