NOTE: Memory footprint of this library is aproximately 128 bytes (global variables)

CONFIGURATION:

#define GESTURES_IMPLEMENTATION Generates the implementation of the library into the included file. If not defined, the library is in header only mode and can be included in other headers or source files without problems. But only ONE file should hold the implementation.

#define GESTURES_STANDALONE If defined, the library can be used as standalone to process gesture events with no external dependencies.
