public void extents_to_pixels (Rectangle? inclusive, Rectangle? nearest)
Converts extents from Pango units to device units, dividing by the SCALE factor and performing rounding.
inclusive rectangle is converted by flooring the x/y coordinates and extending width/height, such that the final rectangle
completely includes the original rectangle.
nearest rectangle is converted by rounding the coordinates of the rectangle to the nearest device unit (pixel).
The rule to which argument to use is: if you want the resulting device-space rectangle to completely contain the original rectangle, pass it in
inclusive. If you want two touching-but-not-overlapping rectangles stay touching-but-not-overlapping after rounding to device
units, pass them in as
rectangle to round to pixels inclusively, or
rectangle to round to nearest pixels, or
