Comprehensive update for Win32/Linux32 dmd-2.053/dmd-1.068+Tango-r5661
===D2===
* added [Try]Immutable/Const/Shared templates to work with differenses in D1/D2 instead of version statements
used these templates to work with strict type storage rules of dmd-2.053
* com.ibm.icu now also compilable with D2, but not tested yet
* small fixes
Snippet288 - shared data is in TLS
===Phobos===
* fixed critical bugs in Phobos implemention
completely incorrect segfault prone fromStringz (Linux's port ruthless killer)
terrible, incorrect StringBuffer realization (StyledText killer)
* fixed small bugs as well
Snippet72 - misprint in the snippet
* implemented missed functionality for Phobos
ByteArrayOutputStream implemented (image loading available)
formatting correctly works for all DWT's cases
As a result, folowing snippets now works with Phobos (Snippet### - what is fixed):
Snippet24, 42, 111, 115, 130, 235, 276 - bad string formatting
Snippet48, 282 - crash on image loading
Snippet163, 189, 211, 213, 217, 218, 222 - crash on copy/cut in StyledText
Snippet244 - hang-up
===Tango===
* few changes for the latest Tango trunc-r5661
* few small performance improvments
===General===
* implMissing-s for only one version changed to implMissingInTango/InPhobos
* incorrect calls to Format in toString-s fixed
* fixed loading \uXXXX characters in ResourceBundle
* added good UTF-8 support for StyledText, TextLayout (Win32) and friends
UTF functions revised and tested. It is now in java.nonstandard.*Utf modules
StyledText and TextLayout (Win32) modules revised for UTF-8 support
* removed small diferences in most identical files in *.swt.* folders
*.swt.internal.image, *.swt.events and *.swt.custom are identical in Win32/Linux32
now 179 of 576 (~31%) files in *.swt.* folders are fully identical
* Win32: snippets now have right subsystem, pretty icons and native system style controls
* small fixes in snippets
Snippet44 - it's not Snippet44
Snippet212 - functions work with different images and offsets arrays
Win32: Snippet282 - crash on close if the button has an image
Snippet293 - setGrayed is commented
and others
Win32: As a result, folowing snippets now works
Snippet68 - color doesn't change
Snippet163, 189, 211, 213, 217, 218, 222 - UTF-8 issues (see above)
Snippet193 - no tabel headers

| 21 /** | |
| 22 * Instances of this class are sent as a result of | |
| 23 * widget traversal actions. | |
| 24 * <p> | |
| 25 * The traversal event allows fine control over keyboard traversal | |
| 26 * in a control both to implement traversal and override the default | |
| 27 * traversal behavior defined by the system. This is achieved using | |
| 28 * two fields, <code>detail</code> and <code>doit</code>. | |
| 29 * </p><p> | |
| 30 * When a control is traversed, a traverse event is sent. The detail | |
| 31 * describes the type of traversal and the doit field indicates the default | |
| 32 * behavior of the system. For example, when a right arrow key is pressed | |
| 33 * in a text control, the detail field is <code>TRAVERSE_ARROW_NEXT</code> | |
| 34 * and the doit field is <code>false</code>, indicating that the system | |
| 35 * will not traverse to the next tab item and the arrow key will be | |
| 36 * delivered to the text control. If the same key is pressed in a radio | |
| 37 * button, the doit field will be <code>true</code>, indicating that | |
| 38 * traversal is to proceed to the next tab item, possibly another radio | |
| 39 * button in the group and that the arrow key is not to be delivered | |
| 40 * to the radio button. | |
| 41 * </p><p> | |
| 42 * How can the traversal event be used to implement traversal? | |
| 43 * When a tab key is pressed in a canvas, the detail field will be | |
| 44 * <code>TRAVERSE_TAB_NEXT</code> and the doit field will be | |
| 45 * <code>false</code>. The default behavior of the system is to | |
| 46 * provide no traversal for canvas controls. This means that by | |
| 47 * default in a canvas, a key listener will see every key that the | |
| 48 * user types, including traversal keys. To understand why this | |
| 49 * is so, it is important to understand that only the widget implementor | |
| 50 * can decide which traversal is appropriate for the widget. Returning | |
| 51 * to the <code>TRAVERSE_TAB_NEXT</code> example, a text widget implemented | |
| 52 * by a canvas would typically want to use the tab key to insert a | |
| 53 * tab character into the widget. A list widget implementation, on the | |
| 54 * other hand, would like the system default traversal behavior. Using | |
| 55 * only the doit flag, both implementations are possible. The text widget | |
| 56 * implementor sets doit to <code>false</code>, ensuring that the system | |
| 57 * will not traverse and that the tab key will be delivered to key listeners. | |
| 58 * The list widget implementor sets doit to <code>true</code>, indicating | |
| 59 * that the system should perform tab traversal and that the key should not | |
| 60 * be delivered to the list widget. | |
| 61 * </p><p> | |
| 62 * How can the traversal event be used to override system traversal? | |
| 63 * When the return key is pressed in a single line text control, the | |
| 64 * detail field is <code>TRAVERSE_RETURN</code> and the doit field | |
| 65 * is <code>true</code>. This means that the return key will be processed | |
| 66 * by the default button, not the text widget. If the text widget has | |
| 67 * a default selection listener, it will not run because the return key | |
| 68 * will be processed by the default button. Imagine that the text control | |
| 69 * is being used as an in-place editor and return is used to dispose the | |
| 70 * widget. Setting doit to <code>false</code> will stop the system from | |
| 71 * activating the default button but the key will be delivered to the text | |
| 72 * control, running the key and selection listeners for the text. How | |
| 73 * can <code>TRAVERSE_RETURN</code> be implemented so that the default button | |
| 74 * will not be activated and the text widget will not see the return key? | |
| 75 * This is achieved by setting doit to <code>true</code>, and the detail | |
| 76 * to <code>TRAVERSE_NONE</code>. | |
| 77 * </p><p> | |
| 78 * Note: A widget implementor will typically implement traversal using | |
| 79 * only the doit flag to either enable or disable system traversal. | |
| 80 * </p> | |

| 104 * For example, setting the detail to <code>TRAVERSE_NONE</code> | |
| 105 * causes no traversal action to be taken. | |
| 106 * | |
| 107 * When used in conjunction with the <code>doit</code> field, the | |
| 108 * traversal detail field can be useful when overriding the default | |
| 109 * traversal mechanism for a control. For example, setting the doit | |
| 110 * field to <code>false</code> will cancel the operation and allow | |
| 111 * the traversal key stroke to be delivered to the control. Setting | |
| 112 * the doit field to <code>true</code> indicates that the traversal | |
| 113 * described by the detail field is to be performed. | |
