* Multitouch handling, allows one of these actions below to work with moving camera at the same time. - Switching hotbar slot; might not work properly - Destroying block (left mouse button) with another finger long-pressed (without pressing the PRI button) - Right mouse trigger with another finger tapped onto the screen (without pressing the SEC button); not working properly yet * Sub-pixel cursor support; not yet checked
