This function creates a QR-code and draws it in a new bitmap, adding a border all around.
-	The QR-code is black on white.
-	The QR-code encodes the message msg with a correction level to be choosen in [[ECL_HIGH]], [[ECL_QUARTILE]], [[ECL_MEDIUM]], [[ECL_LOW]].
-	The higher the correction level, the thinnest the QR-code is.
