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
