"Android Asset Studio" adds extra space when I upload my .png icons, but doesn't when it uses its internal cliparts. Why?

Question

I'm trying to create some nice icons for some Android APP I'm dealing with, and someone directed me to the "Android Asset Studio", that nice online tool which creates full packs of icons ready to be deployed onto my (horridly) fragmented Android project res folder.

I just went to its URL to create my icons:

EDIT: [broken URL as of Oct 2016. Apparently everything has moved into Android Studio] http://android-ui-utils.googlecode.com/hg/asset-studio/dist/icons-actionbar.html#source.type=image&source.space.trim=1&source.space.pad=0&name=ic_action_stickers&theme=custom&color=000%2C80

Then I noticed something a bit annoying: When using its internal cliparts, they appear perfectly trimmed/clipped/padded (that is, 0 padding), but when I try to upload my simple transparent .png files, this tool always adds some annoying padding space around my final icons, no matter what.

Is it normal? I've played with "trim/no-Trim" and "padding" buttons, but no luck (it just even makes things a bit worse).

Any hint? Am I missing something?

Thanks.

A couple of days ago I made this:

http://reiszecke.github.io/AndroidAssetStudioFullsize/

when you choose >> Launcher icons << Full Size edit you will be able to get your files on full size without any padding. I didn't do it for every shape tho

EDIT: I need to mention again it only works for the shape NONE, a bit for BEVEL and maybe for CIRCLE

EDIT2: I do not need Google's ugly hipster dogears, rounded corners or 3D-style presets. Use photoshop if you think you need to be trendy. This is why I said I did not do it for every shape. The only purpose of my mod is to save the time you would waste converting your icon into every single icon-size. Instead of complaining, just do your own for the other shapes. The code is public, make something of it.
