touchgfx::Circle::setCapPrecision() method

@fn void Circle::setCapPrecision(const int precision); Sets the precision of the ends of the Circle arc. Sets a precision of the ends of the Circle arc. The precision is given in degrees where 180 is the default which results in a square ended arc (aka "butt cap"). 90 will draw "an arrow head" and smaller values gives a round cap. Larger values of precision results in faster rendering of the circle.
