Migrate to Makepad 2.0, from Live DSL to Splash script

[kevinaboos]

Nothing in mobile view mode has been tested due to the fact that AdaptiveView is not yet ported to Makepad 2.0. Seems to be fully working now!

Widgets that are known to be working (via manual verification/fixes):

• Makepad-internal
  • Tooltip (fixed by me in Fix Tooltip behavior and structure. Add CalloutTooltip widget makepad/makepad#881)
  • Hideable dock tab bars (fixed by me in Support hiding a dock tabs bar makepad/makepad#937)
  • CalloutTooltip (added by me in Add missing callout tooltip file makepad/makepad#882)
  • Icon
    • Actually this is still broken, waiting on a Makepad-level fix. Okay, now been fixed.
  • IconRotated (added by me in FIx Icon, improve to support IconRotated, expose geom in draw_svg makepad/makepad#883)
    • Removed from Robrix, no longer needed.
  • TextInput: color_empty_hover/color_empty_focus are not being used. Fixed by me in TextInput: actually use color_empty_hover/focus in draw_text shader makepad/makepad#927
• HtmlLink (or perhaps Robrix's link wrapper)
  • Both have been fixed: Fix HtmlLink attribute init to handle any attr order makepad/makepad#948
• Tooltip behavior: hover-in doesn't take effect until clicking on the UI a few times
  • TODO: check if this is the main Tooltip widget or if it's a problem with our CalloutTooltip wrapper fixed: fix tooltip by force-drawing the draw list upon show/hide makepad/makepad#950
• restoring the dock layout upon app boot does not yet work
• /src/shared/
  • Avatar (fixed now, after my fix to CircleView, Fix circle view makepad/makepad#887)
  • bouncing dots: animation does not run
  • collapsible header: everything working except unread badge fixed
  • confirmation modal
  • expand arrow (newly created for 2.0)
  • helpers
  • html or plaintext
    • needs some formatting fixes to make the text spacing look nice again
      • Fixed by me here in Fixed several issue in text drawing, layout, and text flow. makepad/makepad#970 and Ensure that the Html <br> tag obeys current line spacing settings makepad/makepad#971
    • RobrixHtmlLink
    • MatrixHtmlSpan: implemented but not fully tested fully works
  • icon_button
    • RobrixIconButton: works, but hover/down styling could be improved.
      • TODO: Makepad's new Button no longer has a hover animator for draw_icon, so the hover and down instances used in RobrixIconButton's draw_icon shader actually never get modified.
    • IconButton: removed, everything now uses RobrixIconButton
  • ImageViewer: rotation works. Panning and scroll-to-zoom do not work.
  • jump to bottom button
  • mentionable text input: this has been replaced with a mock wrapper around a regular RobrixTextInput. We'll re-do it entirely in the near future.
  • popup list of notifications (fix apply_over)
  • restore status view
  • room filter input bar
  • styles
    • RobrixTextInput
    • SimpleTextInput: removed, now use RobrixTextInput everywhere

  • editing pane
  • event reaction list: mostly works, just need to fix borders, and increase emoji font size fully works
  • event source modal
  • home screen
  • Invite modal
  • invite screen
  • light themed dock: needs a full rework done
  • link preview
  • loading pane
  • location preview: buttons aren't aligned properly fixed

    • missing some entry labels and icons fixed now: fix SVG handling to support SVG files with fill "none" makepad/makepad#961
  • room image viewer
  • room read receipt
  • room screen
    • Message
    • CondensedMessage
    • ImageMessage
    • CondensedImageMessage
  • rooms list entry: fully works but the styling code in update_preview_colors() was completely removed. Need to restore it. done
  • rooms list header
  • rooms list: mostly working, except redraw isn't consistent seems to be fully working now
  • It also does that old portal list behavior where scrolling upwards when you're at the bottom of the list will auto-jump to the top of the list. fixed
  • rooms sidebar
  • search messages: not yet used
  • space lobby
  • spaces bar: works on desktop, untested on mobile

    • log out button icon does not show properly (ICON_LOGOUT) fixed by me: fix SVG handling to support SVG files with fill "none" makepad/makepad#961
• FadeView: fully removed, no longer needed.
• src/profile/
  • User profile sliding pane: now works perfectly.
• join leave room modal
• verification modal
• app.rs: fully works, but the code changes for the image viewer can be re-simplified back to what they were (pending testing)

Moving ahead with the merge! The only known issues are:

• ImageViewer: panning (click and drag) and scroll-based zoom don't work.
  • Rotation within the Makepad Image widget might also not be 100% correct, not sure.
• Modals: scrolling pierces through the modal, but that was a problem before hand too (in Makepad 1.0).
• MentionableTextInput: the user-mention feature has been removed, but will be added back shortly.
