This is the release of the class that extends the capability of screen buttons. The class is very similar in usage to Adafruit_GFX_Button. Except its initialization rest of the usage is seemles to the Adafruit's. Class allows for displaying buttons from uint8_t masks with defined rgb565 color, or it can display uint16_t bitmaps as buttons(with masks or without). Together with the class comes .cpp tool for exporting mask and bitmap arrays from .bmp files on usual PC.
