|
|
// * (0, 0) - will automatically calculate a size that fits the text on one line (expand horizontally)
|
|
// * (x != 0, 0) - wrap text so that it does not reach beyond x. Will automatically calculate a vertical size (expand vertically).
|
|
// * (x != 0, y <= fontHeight) - will truncate text so it fits within this box.
