The Squared update [Part 3] - 1.4.3

• Added preview mode to Squared - to see how the image looks in realtime
• Added "Save and stop" button - to stop generation and save as is
• SQU & SQV format version 2: optimization enabled for images with objects which have constant rotation or constant size
• Added classes for Squared to Level.h: Frame, FrameAnimation, FrameAnimator - for opening .squ and .sqv
• Added 2 new examples for the new classes mentioned above
• Added a frame rate limit to all examples
• Added an option to draw grid before the scene - the new default
• Added the backup option - the idea is too have many copies of a level since level editor files are quite small, something similar to Git - you can travel back in backups whenever you'd like
• Changed select outline thickness from 1px to 3px
• Added the option to disable checking for updates at startup
• Fixed a checking for updates version bug
• Fixed some variables not resetting after switching levels
• Fixed a control + drag bug with items that aren't textures
