I will try to come up with a better solution for the next plugin release.

Thanks for the quick reply and the effort to solve this!
I did as you suggested and used the command line interface. It did the job avoiding the borders, altough one last problem remains: it is altering the gif image.
When I visualize the KFX (azw8) on KindlePreviewer (see the attached screenshot), it looks perfect, just like the ePub. But, when I sideload it to the device, on the Kindle Paperwhite screen, the gif has a gray background (see the screenshot attached). This gif is supposed to be tranparent. It shows properly on the device when I use AZW3 format, or when I convert it using KindlePreviewer directly (altough it will save on MOBI format).
How can I configure the convertion so it doesn't touch the images? Through Calibre, I used your suggestion to change the output page configuration to "Tablet", but it still causes the gray background.
I am intrigued that when KindlePreviewer exports the MOBI file, the image looks fine on the device. It looks like the KFXOutput plugin is changing the image in some way, after the KindlePreviewer does his job (compression, maybe?).
