use of pythagoras.f.IRectangle in project playn by threerings.

the class TextBlock method getBounds.

/** Computes the bounds of a block of text. The {@code x} component of the bounds may be
   * positive, indicating that the text should be rendered at that offset. This is to account for
   * the fact that some text renders to the left of its reported origin due to font
   * extravagance. */

    // some font glyphs start rendering at a negative inset, blowing outside their bounding box
    // (naughty!); in such cases, we use xAdjust to shift everything to the right to ensure that we
    // don't paint outside our reported bounding box (so that someone can create a single canvas of
    // bounding box size and render this text layout into it at (0,0) and nothing will get cut off)

        // we use layout.width() here not bounds width because layout width includes extra space
        // needed for lines that start rendering at a positive x offset whereas bounds.width() is
        // only the precise width of the rendered text
