| 84 * Class <code>GC</code> is where all of the drawing capabilities that are | |
| 85 * supported by SWT are located. Instances are used to draw on either an | |
| 86 * <code>Image</code>, a <code>Control</code>, or directly on a <code>Display</code>. | |
| 87 * <dl> | |
| 88 * <dt><b>Styles:</b></dt> | |

| 91 * | |
| 92 * <p> | |
| 93 * The SWT drawing coordinate system is the two-dimensional space with the origin | |
| 94 * (0,0) at the top left corner of the drawing area and with (x,y) values increasing | |
| 95 * to the right and downward respectively. | |
| 96 * </p> | |
| 97 * | |
| 98 * <p> | |
| 99 * Application code must explicitly invoke the <code>GC.dispose()</code> | |
| 100 * method to release the operating system resources managed by each instance | |
| 101 * when those instances are no longer required. This is <em>particularly</em> | |
| 102 * important on Windows95 and Windows98 where the operating system has a limited | |
| 103 * number of device contexts available. | |
| 104 * </p> | |
