| 88 | + * surface and changes to the overall state of the pixels - such | |
| 89 | + * as becoming invalid or losing the surface. The delegate is | |
| 90 | + * marked "dirty" whenever the setSurfaceLost() or invalidate() | |
| 91 | + * methods are called and should also be marked "dirty" by the | |
| 92 | + * rendering pipelines whenever they modify the pixels of this | |
| 93 | + * SurfaceData. | |
| 94 | + * <p> | |
| 95 | + * If you get a StateTracker from a SurfaceData and it reports | |
| 96 | + * that it is still "current", then you can trust that the pixels | |

| 152 | + * The Object used as this key should be as unique as it needs | |

| 162 | + * sharing requirements. For instance, X11 pixmaps can be | |
| 163 | + * shared on a given screen by any GraphicsConfiguration that | |
| 164 | + * has the same depth and SurfaceType. Multiple such GCs with | |
| 165 | + * the same depth and SurfaceType can exist per screen so storing | |
| 166 | + * a different cached proxy for each would be a waste. One can | |
| 167 | + * imagine platforms where a single cached copy can be created | |

| 202 | + * <li> destSD uses its "blit proxy key" (if set) to look for | |
| 203 | + * some cached data stored in the source SurfaceManager | |
| 204 | + * <li> If the cached data is null then makeProxyFor() is used | |
| 205 | + * to create some cached data which is stored back in the | |
| 206 | + * source SurfaceManager under the same key for future uses. | |
| 207 | + * <li> The cached data will be a SurfaceDataProxy object. | |
| 208 | + * <li> The SurfaceDataProxy object is then consulted to | |
| 209 | + * return a replacement SurfaceData object (typically | |
