// AlignText calculates the initial position of the text
// output depending on str length and available width.
// The str is truncated in case of its lenght greater than
// width. Function returns shift that should be added to
// original label position before output instead of padding
// the string with spaces. The reason is to make possible
// to draw a label aligned but with transparent beginning
// and ending. If you do not need transparency you can
// add spaces manually using the returned shift value
