Patch of demo D-11: less clipping, more clipping, better names — icosi-do Steam update #103897

Just a small patch as I'm working my way through a list of recommendations by Tilt Five. The movement and scaling of the puzzle and menu text has been limited to avoid clipping at the edges of the gameboard. If you get too close to any rods, they are now clipped to avoid visual discomfort. (I accidentally published an intermediate version with too much clipping - the latest patch should fix that.) The menu point "SETTINGS > TILT FIVE" has been renamed to "SETTINGS > AR GLASSES" to take into account that one day the game might support other AR glasses as well (and to avoid using a trademark without the ™ sign). The test performed with SETTINGS > AR GLASSES > CHECK SYSTEM has been improved to detect whether the correct driver (version 1.2.1) has been installed. If the test doesn't find the correct driver, it now responds: "NO DRIVER 1_2_1" Also, the manual has been updated. As always, plea...
