From 4c521317ff86de9b68aa79baf2e2e5d10a0b21cb Mon Sep 17 00:00:00 2001 From: Eric Rowell Date: Sun, 1 Jul 2012 16:25:02 -0700 Subject: [PATCH] Text shape is no longer a group made up of a Rect and Shape. The complexity overhead out-weighs the inelgance of duplicating a dozen lines of the Rect shape. --- dist/kinetic-core.js | 148 ++++++++++++++++++--------------------- dist/kinetic-core.min.js | 2 +-
