pangoLayoutLineGetPixelExtents

Description

Computes the logical and ink extents of layout.line in device units. This function just calls pangoLayoutLineGetExtents followed by two pangoExtentsToPixels calls, rounding ink.rect and logical.rect such that the rounded rectangles fully contain the unrounded one (that is, passes them as first argument to pangoExtentsToPixels).

`ink.rect`	[`PangoRectangle`] rectangle used to store the extents of the glyph string as drawn, or `NULL`
