// carried in the same resolution as the final rendering. This is done because

// the text glyph positions are snapped to the nearest pixels sharp rendering.
|
||||
//
|
||||
// The local space means that values are not rotated or scale as per the current
|
||||
// transformation. For example if you set font size to 12, which would mean that
|
||||
// line height is 16, then regardless of the current scaling and rotation, the
|
||||
// returned line height is always 16. Some measures may vary because of the scaling
|
||||
// since aforementioned pixel snapping.
|

//
|

//
