Launcher tile dragging shouldn't be masked

I am proposing a fix for this bug. The fix is to increase the right margin by 10 pixels, allowing the icons to be dragged outside of the launcher while they are still resisting the pull.

If it looks good to you, land it so we can check it in a daily. Or
publish to a PPA for review.

Increasing the right margin by 10 pixels has a major impact on the available space for the main content. Much better limit the maximum movement of the tile before it snaps out.

To second Christian, please don't change the sizing of the Launcher or icons. The prototype is correct, the icon should travel proportionally to mouse movement (not 1:1, more like 1:10 but definitely 1:1 for the first pixel only, so n mod 10 +1) until it crosses the launcher boundary then pops.

I am not sure what 10px Jay was talking about, but I don't think it was the user visible width of the launcher... At any rate I can no longer reproduce the masking.

On the prototype/specs, before it pops, can go over the content, if this is not possible (for time etc..) just reduce the movement of the tile so that it is always visible before it pops.

Actually as far as I can tell it does go ~5px or so over the content before it pops. That said, when I use a very bright wallpaper I can see some rendering artefacts around the tile just before it pops. Very subtle, so not a huge deal, but they are definitely there.

When you say "over the content", do you mean "off the launcher
background onto the window next to it"?

@Mark: yes

As you can see from the screenshot, some pixels to the right of the tile are not visible. As soon as a tile is dragged, should look like it is on a top layer, thus should always be entirely visible.

(The tile can actually be cut even more then showed on the screenshot)

should never happen, because the icon should pop off rather than sliding
under the edge of the launcher pane.

The 10 pixels margin does not affect the main content area. It only has an effect on the rendering process of the launcher. More precisely, it affects the caching algorithm that was created to avoid rendering the launcher unnecessarily.
