0.5.2

• Various invasive rewrites (things might be unstable for a while)
• New reference viewer (top screen):
  • Add references from your browser, up to 99
    • Images are converted into 3ds format by browser
    • Any image format your browser can read is usable
    • If your browser has security which obfuscates the canvas (librewolf, etc) you will need to disable that for this page
  • Reference storage is reused per session, no worries about cleaning up data
  • Can pull in references from previous sessions rather than starting anew
  • Change reference image with R + Start + Up/Down
• Show error on too-large upload to 3ds (not size of image; you should not see this error regardless!)
• Show error on too-large reference image (again not size of uploaded image, just a safety check!)
• Fix text overflow in image upload page
• Fix memory leak when exporting too often (only an issue with PNG export, bug has existed almost since the beginning)
