1. LayoutDeserializeErrorInvalidValue :: LayoutDeserializeError

   gi-pango	GI.Pango.Enums

   A JSon value could not be interpreted

2. ScriptBuhid :: Script

   gi-pango	GI.Pango.Enums

   Buhid

3. ScriptInvalidCode :: Script

   gi-pango	GI.Pango.Enums

   a value never returned from scriptForUnichar

4. ScriptSiddham :: Script

   gi-pango	GI.Pango.Enums

   Siddham. Since: 1.40

5. isZeroWidth :: (HasCallStack, MonadIO m) => Char -> m Bool

   gi-pango	GI.Pango.Functions

   Checks if a character that should not be normally rendered. This includes all Unicode characters with "ZERO WIDTH" in their name, as well as *bidi* formatting characters, and a few other ones. This is totally different from unicharIszerowidth and is at best misnamed. Since: 1.10

6. layoutGetWidth :: (HasCallStack, MonadIO m, IsLayout a) => a -> m Int32

   gi-pango	GI.Pango.Objects.Layout

   Gets the width to which the lines of the PangoLayout should wrap.

7. layoutSetWidth :: (HasCallStack, MonadIO m, IsLayout a) => a -> Int32 -> m ()

   gi-pango	GI.Pango.Objects.Layout

   Sets the width to which the lines of the PangoLayout should wrap or ellipsized. The default value is -1: no width set.

8. rendererDrawTrapezoid :: (HasCallStack, MonadIO m, IsRenderer a) => a -> RenderPart -> Double -> Double -> Double -> Double -> Double -> Double -> m ()

   gi-pango	GI.Pango.Objects.Renderer

   Draws a trapezoid with the parallel sides aligned with the X axis using the given PangoRenderer; coordinates are in device space. Since: 1.8

9. fontMetricsGetApproximateCharWidth :: (HasCallStack, MonadIO m) => FontMetrics -> m Int32

   gi-pango	GI.Pango.Structs.FontMetrics

   Gets the approximate character width for a font metrics structure. This is merely a representative value useful, for example, for determining the initial size for a window. Actual characters in text will be wider and narrower than this.

10. fontMetricsGetApproximateDigitWidth :: (HasCallStack, MonadIO m) => FontMetrics -> m Int32

    gi-pango	GI.Pango.Structs.FontMetrics

    Gets the approximate digit width for a font metrics structure. This is merely a representative value useful, for example, for determining the initial size for a window. Actual digits in text can be wider or narrower than this, though this value is generally somewhat more accurate than the result of fontMetricsGetApproximateCharWidth for digits.
