[ Upstream commit 291ddeb621e4a9f1ced8302a777fbd7fbda058c6 ]

Currently the switch statement for format->cpp[0] value 4 assigns color_index which is never read again and then falls through to the default case and returns. This looks like a missing break statement bug. Fix this by adding a break statement.
