| 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. |
