These functions provide support for drawing points, lines, arcs and text
onto what are called 'drawables'. Drawables, as the name suggests, are things
which support drawing onto them, and are either GdkWindow or GdkPixmap
objects.
Many of the drawing operations take a GdkGC argument, which represents a
graphics context. This GdkGC contains a number of drawing attributes such
as foreground color, background color and line width, and is used to reduce
the number of arguments needed for each drawing operation. See the
Graphics Contexts section for
more information.
Some of the drawing operations take Pango data structures like PangoContext,
PangoLayout or PangoLayoutLine as arguments. If you're using GTK+, the ususal
way to obtain these structures is via gtkWidgetCreatePangoContext or
gtkWidgetCreatePangoLayout.
GdkDrawableGdkPixmap, a GdkBitmap,
or a GdkWindow.
GdkSegmentgdkDrawSegments
function.
GdkSegment is a transparent-type.

GdkTrapezoidgdkDrawTrapezoids.
The trapezoids used here have parallel, horizontal top and
bottom edges.
GdkTrapezoid is a transparent-type.
