This PR refactors our clipboard handlers. It should simplify the way that things work and better handle the difference between how the native API events are handled vs. the browser's clipboard API events.  Everything that used to be supported now also still works. In addition, we now have several useful features: ### Multiline text can be pasted into the app When pasting text that contains more than one line, the text is pasted correctly; even if the clipboard also includes HTML data. Previously, we would try to paste HTML data if we found it, because that data might contain tldraw's own content as a comment; but if that failed, we would paste the data as text instead. This led to pasting text that lost lots of information from that text, such as line breaks and indentations. ### Multiline text shapes are aligned correctly When pasting raw text that has more than one line, the text will be left aligned—or right aligned if the text is likely from a RTL language.  ### Common minimum indentation is removed from each line  This is something that absolutely every app should implement, but here we go. When multiline text has "common indentation" on each line, which is often the case when pasting text from code, then that indentation is removed from each line. ### Auto wrapping for big pastes When a line has no text breaks but a lot of text, we now set the width of the text shape.  ## How it works A `ClipboardThing` is the common interface for things that we found on the clipboard, native or otherwise. Both `handlePasteFromClipboardApi` and `handlePasteFromEventClipboardData` parse out `ClipboardThing`s and pass them to `handleClipboardThings`. <img width="905" alt="image" src="https://github.com/tldraw/tldraw/assets/23072548/fd087539-edbb-4527-b5ff-ca7d7c1726b2"> A `ClipboardResult` is the result of processing a `ClipboardThing`, and usually contains text and other information about that text. We make decisions on what to create based on which `ClipboardResult`s we find. When pasting text, we check to see whether the result would be bigger than the viewport, or if the text is multiline, or if the text is of an RTL language by testing certain common RTL characters. We make some adjustments based on those factors, ensuring that the top-left corner of the text is on screen and reasonably positioned within the viewport if possible. ### Change Type - [x] `minor` — New Feature ### Test Plan 1. Copy and paste shapes 2. Copy and paste text from elsewhere into the app 3. Copy and paste images from elsewhere into the app 4. Try on different browsers ### Release Notes - Improves clipboard logic when pasting text - Adds support for pasting multi-line text - Adds maximum widths when pasting single-line text - Adds support for RTL languages when pasting multi-line or wrapped text - Strips leading indentation when pasting text |
