Snap

• more optimizations for collision detection
• Catalan translation update

optimized collision detection

v5.2.0:

• New Features:
  • new media creation primitives:
  • new primitive in "looks": NEW COSTUME from a list of pixels and dimensions, allowing CURRENT
  • new primitive in "sound": NEW SOUND from a list of samples
  • added selectors for sprites' and the stage's bounding box (LEFT, RIGHT, TOP, BOTTOM) to MY dropdown
  • new experimental entry for "green flag pressed" in the BROADCAST block's dropdown when the shift key is pressed
• Notable Changes:
  • running STOP ALL now also toggles (pauses and resumes) all generic WHEN hat blocks (just like pressing the stop button)
  • changed default name for new costumes created with STRETCH etc. to localized 'costume'
• Notable Fixes:
  • loading a project that fires STOP ALL from a WHEN hat block no longer "hangs" Snap
  • fixed pixel-manipulation distortions on newly imported hi-res images
  • assert that dimensions given for STRETCH are finite numbers (avoid crash)
  • disabled direct editing of list watchers for non-literal typed lists (such as costumes, avoids unloadable projects)
  • fixed occasional "dead clicks" on buttons and menu items
• Translation Updates:
  • English
  • German

  • "temporary?" attribute is now programmatically settable (in the SET->my... block)
• Notable Changes:
  • generated costumes that are not in the wardrobe are now made persistent in the project (saved & restored)
• Notable Fixes:
