From: fmalita@google.com Date: Thu, 13 Jun 2013 20:59:14 +0000 (+0000) Subject: Expose debugger backend classes externally. X-Git-Tag: submit/tizen/20180928.044319~12098 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=86681b37bd20204e47a492119b345c01d00bc939;p=platform%2Fupstream%2FlibSkiaSharp.git Expose debugger backend classes externally. SkDebugCanvas & friends are useful beyond the Qt debugger app - Chromium's picture inspector (in development) is at the point where it could take advantage of it. This patch moves SkDrawCommand, SkDebugCanvas & SkObjectParser from trunk/debugger to trunk/src/utils (since several tools already use these, this seems appropriate), and makes SkDrawCommand & SkDebugCanvas' symbols visible externally (SK_API).
