Removing the [WIP]. Not addressed here — how to generate a sourcemap for concatenated CSS files (e.g. the CSS bundle generated by rollup-plugin-svelte). Probably outside Svelte's remit, though it's a little annoying to have to keep decoding, manipulating, combining and reencoding sourcemap mappings. (Sourcemaps are a pain.) |

The immediate goal of this PR is to add support for CSS sourcemaps. The approach I'm taking is to move all the CSS logic into a new
Stylesheetclass, which is responsible for creating/transforming a separate MagicString instance.This will make it a bit easier to remove unused rules altogether, and do e.g. whitespace removal. Ultimately we could even have multiple stylesheets attached to a component (for example, if a component had two or more
<link rel='stylesheet'>tags, if we get round to that).
