* Upgrade TypeScript, ESLint, and other dependencies
This also cleans up various other files where newer ESLint rules complained
* Set CI and CD to use Node.js version 16
* Small tweak
* Fix CD version printing
* Add nvm version for Cloudflare Pages
* Implement undo and redo
* Create more save points and hook up menu entry
* Fix operation ordering
* Remove debug statement
* Fix folder changed order
* Don't store overlays in the history chain
* Keep selection
* Add a stroke width option to the Line Tool
* Fix title case for line options
* Add px unit to line stroke width
* Add stroke width to pen tool
* Rename stroke width to weight
* Change number input width to min-width
* Remove the word "stroke" from "stroke weight"
* Add support for saving a document
This is similar to the "export" functionality, except that
we store all metadata needed to open the file again.
Currently we store the internal representation of the layer
which is probably pretty fragile.
Example document:
```json
{
"nodes": {},
"root": {
"blend_mode": "Normal",
"cache": "...",
"cache_dirty": false,
"data": {
"Folder": {
"layer_ids": [
3902938778642561358
],
"layers": [
{
"blend_mode": "Normal",
"cache": "...",
"cache_dirty": false,
"data": {
"Shape": {
"path": [
{
"MoveTo": {
"x": 0.0,
"y": 0.0
}
},
{
"LineTo": {
"x": 1.0,
"y": 0.0
}
},
{
"LineTo": {
"x": 1.0,
"y": 1.0
}
},
{
"LineTo": {
"x": 0.0,
"y": 1.0
}
},
"ClosePath"
],
"render_index": 1,
"solid": true,
"style": {
"fill": {

"transform": {
"matrix2": [
223.0,

* Add support for opening a saved document
User can select a file using the browser's file input selector.
We parse it as JSON and load it into the internal representation.
Concerns:
- The file format is fragile
- Loading data directly into internal data structures usually creates
security vulnerabilities
- Error handling: The user is not informed of errors
* Serialize Document and skip "cache" fields in Layer
Instead of serializing the root layer, we serialize the
Document struct directly. Additionally, we mark the
"cache" fields in layer as "skip" fields so they
don't get serialized.
* Opened files use the filename as the tab title
* Split "new document" and "open document" handling
Open document needs name and content to be provided so having a
different interface is cleaner. Also did some refactoring to reuse code.
* Show error to user when a file fails to open
* Clean up code: better variable naming and structure
* Use document name for saved and exported files
We pass through the document name in the export and save
messages. Additionally, we check if the appropriate file
suffixes (.graphite and .svg) need to be added before
passing it to the frontend.
* Refactor document name generation
* Don't assign a default of 1 to Documents that start with something
other than DEFAULT_DOCUMENT_NAME
* Improve runtime complexity by using binary instead of linear search
* Update Layer panel upon document selection
* Add File>Open/Ctrl+O; File>Save (As)/Ctrl+(Shift)+S; browse filters extension; split out download()/upload() into files.ts; change unsaved close dialog text
