Changes

• Updates to js-draw 0.17.3 from version 0.15.0.
  • Fixes canvas not resizing correctly on screen rotation.
  • Improves the overflow menu on small screens.
  • Other bug-fixes.
• Adds a default background color to make it clearer what is and what isn't in an image.
  • Changing the background color under "Document" > "Background Color" changes the background color for new images.
  • Currently, this background color is mostly transparent. Perhaps it should, instead, be a solid color.
• Fixes invisible selection in some Aritim dark themes.
