There was a limitation that TIFF input/output with added depth must be 1 channel.It is not documented. Indirectly cvtColor() gives an error that unsupported depth is entered. This is a confusing error for imread/imwrite users. As a related work, 3/4 channel will be supported at this fix. |

- Replaced BGR/RGB data reordering implementation from copying from SRC to DST to using mixChannel(). - Defined an enum to represent Mat types as strings(e.g. CV_8UC1, CV_32FC2, ...) instead of numbers. - (For test) Changed the success/failure judgment of imdecode from dst.empty() to the return value of function.
