/*
A graphics2d struct is both simpler and uglier than a graphics
struct.
Most of the graphics2d drawing state is held in the referenced cairo_t
and corresponding cairo_surface_t, so we can ignore it.
In addition to the cairo_t, we need to hold an extra reference to the
underlying GdkDrawable so its refcount matches the lifecycle of the java
Graphics object which is peering with us; also a reference to a byte
buffer and cairo_surface_t which contain the pattern you're drawing from
(if it exists).
Finally, it is possible that we are using a non-RENDER capable X server,
therefore we will be drawing to an cairo_surface_t which is actually a
pixbuf. When this is the case, the pointer to a GdkPixbuf will be
non-NULL and any drawing operation needs to be bracketed by pixbuf
load/save operations. If the GdkPixbuf pointer is NULL, we will treat
the cairo_surface_t as RENDER-capable.
