🚀 Features

Multiple texture atlas page support (#4244, #4252, #4274) via @​Tyriar

Instead of there being a hard cap of 1024x1024 on the size of the texture atlas backing the canvas and webgl renderers, multiple textures are now supported. Each individual texture is now 512x512 which allows faster uploading to the GPU and will continually merge until the maximum of 4096x4096 is reached.

The benefits in simple terms of this change are:

• Less time from drawing a glyph to rendering it
• Less CPU is used when lots of glyphs are used
• Essentially unlimited space for glyphs, which is good for certain use cases but will also let us explore things like "perfect" dotted and curvy underlines in the future

Here is an example of a 512x512 texture atlas page right after the terminal has loaded and printed a powerline-based prompt:

And here is the 1024x1024 page after a lot of glyphs have rendered:

Slash and triangle custom glyphs (#4313) via @​Tyriar

Eight new powerline extra custom glyphs are supported:

New option scrollOnUserInput (#4289) via @​JasonXJ

You can now specify whether to scroll to the bottom of the terminal on user input, previously this was the default and only behavior. This new setting is enabled by default.

const term = new Terminal({ scrollOnUserInput: false });
