Make ConvTransProjection support for dilation.

[wanghaoshuang]

We calculate output size of ConvTransProjection with origin filterH_ and filterW_, but not take into consideration dilation.
It should be wrote as:

imageH_ = imageSize(outputH_,
                        (filterH_ - 1) * dilationH_ + 1,
                        paddingH_,
                        strideH_,
                       /* caffeMode */ true);

And, outputSize and imageSize are not always reciprocal, so we should't use origin IMAGE_SIZE as ConvTransProjection output size while using output_x as input size.

Excellent!
