Makes debugging issues in conversion from screen space
to diagram space easier.
Only adding english translations as I do not speak the
other languages.
During testing I accidentally managed to submit `NaN` as a pan
coordinate. This had the unfortunate side effect of bricking the
editor.
Given the serverity of an accidental `NaN` and that `NaN`s are not
impossible considering the amount of math involved in mouse move
operations, this commit introduces a simple validation step.
The new validation step should additionally be able to unstuck
anyone who have happened into this state by accident already.
This is basically a migration from mouse events to
[pointer events](
https://developer.mozilla.org/en-US/docs/Web/API/Pointer_events
).
The `PointerEvent` interface inherits all of the `MouseEvent`
properties, meaning that existing code can essentially be left
as-is. The only major change is making sure we only respond to the
"primary" pointer.
Known issues include:
* stylus hover is not detected
* touchscreens do not have a concept of hover, making it difficult
to e.g. resize areas
* no touch gesture support, e.g. "pinch-to-zoom"
Some mobile browsers (e.g. chrome) uses collapsing url bars (the
bar collapses when you scroll). In such cases, `100vh` typically
refers to the full height of the viewport when the url bar is
collapsed (see also `svh`, `lvh` and `dvh`, e.g. at
<https://ishadeed.com/article/new-viewport-units/#the-small-large-and-dynamic-viewport-units>
). This meant that on my tablet, the editor would extend below the
visible page until I scrolled it into view.
This commit re-uses a fix from some of my other projects
(specifically
<5c7e788d40/src/styles/globals.css (L14-L28)>
) where the root element is set to fill 100% height. This avoids
dealing with viewport units altogether. On my tablet, this means
that the url bar is visible and that the editor does not extend
below the visible page.
@1ilit started making similar changes in 4cc0811.
This commit performs a full search and replace for
`drawdb.vercel.app` to `drawdb.app`, fixing remaining "bad" urls.
