huge cleanup, support for SetSizeLimits, support for truncating strings, numerous decorator bug fixes, Layer does not draw when view color is B_TRANSPARENT_COLOR, cleaner dispatching of mouse events to the WinBorder in RootLayer, commented the char map selection in the font server, as it seems glyph lookup by unicode index works much better with the default map git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12945 a95241bf-73f2-0310-859d-f6bbb57e9c96 2005-06-03 19:50:30 +00:00			`/*`
* Replace the truncate_string() helper function with a new, simplified version. * Remove no longer necessary support functions. * The new version uses a single BString as input/output parameter and only modifies that one by removing non-fitting chars and inserting the ellipsis where appropriate, so avoids copying around bytes/chars/strings in a few places. It uses the new Chars functions of BString so also no need for manual multibyte handling. * Adjusted the BFont and ServerFont usage of truncate_string() which are both simplified by using the single BString. It avoids a lot of temprary allocations and string copying. The char * version of BFont GetTruncatedStrings() now uses the BString version and not the other way around anymore which requires us to allocate temporary BString objects, it's not worse than before though. * This fixes a bunch of problems with the previous functions like always prepending the ellipsis for B_TRUNCATE_BEGINNING, crashing on short enough widths, violating the width in the B_TRUNCATE_END case when the width was short enough, non-optimal truncation in a few cases and sometimes truncation where none would've been needed. Also fixes #4128 which was a symptom of the broken B_TRUNCATE_BEGINNING. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35381 a95241bf-73f2-0310-859d-f6bbb57e9c96 2010-02-01 18:43:03 +00:00			`* Copyright 2010, Michael Lotz <mmlr@mlotz.ch>.
