This updates any internal glyph cache textures as necessary to be able to render the given @layout. This api should be used to avoid mid-scene modifications of glyph-cache textures which can lead to undefined rendering results. A #PangoLayout Create a [class@Pango.Context] for the given @font_map. the newly created context: free with [method@GObject.Object.unref]. a #CoglPangoFontMap Retrieves the [class@CoglPango.Renderer] for the passed @font_map. a #PangoRenderer a #CoglPangoFontMap Creates a new font map. the newly created #PangoFontMap Sets the resolution for the @font_map. This is a scale factor between points specified in a [struct@Pango.FontDescription] and Cogl units. The default value is %96, meaning that a 10 point font will be 13 units high. (10 * 96. / 72. = 13.3). a #CoglPangoFontMap The resolution in "dots per inch". (Physical inches aren't actually involved; the terminology is conventional.) Draws a solidly coloured @layout on the given @framebuffer at (@x, @y) within the `framebuffer`'s current model-view coordinate space. A #CoglFramebuffer to draw too. a #PangoLayout X coordinate to render the layout at Y coordinate to render the layout at color to use when rendering the layout Draws a solidly coloured @line on the given @framebuffer at (@x, @y) within the `framebuffer`'s current model-view coordinate space. A #CoglFramebuffer to draw too. a #PangoLayoutLine X coordinate to render the line at Y coordinate to render the line at color to use when rendering the line
