So... should I add it or not?

You mean edge scenarios right? It shouldn't be a problem for inner tiles,
since you can just duplicate the pattern to fill the missing part, and
Inkscape will still cut it more or less correctly.

How about this? You can skew, but if you mess with the handles, the
tile snaps to 90 degrees angle again. It becomes skewed again if you
go back to P1 or P2.

(I don't envy the person who wants to try to program the tiles...)

Hmm... I'll leave it in the design as a "really low priority feature", and we
can just wait and see if anybody actually requests the feature one day.

True. Leaving dynamics out made the design conception much easier,
but I realized that having to go back and add dynamics separately would
be annoying in the end. Here's what I propose:

http://postimage.org/image/4235075wd/

The solution is that little dot thing in the corner of each frame. Initially
I was worried that it'd get in the way, but then I realized that until rendering
is done, those frames are empty anyway. They're also invisible outside
of the render mode.

Each dot offers a visual representation of opacity, blur and HLS. Mouse-over
gives exact values. Double-click to define exact values.

At this point I hope the programing folks can answer a few questions about
interpolation:

1. It is possible to define interpolation over both rows And columns using just
a start tile and a reference tile (example: a base tile at the upper-left and a
reference tile and the bottom-right). The current tiling dialogue forces you to
define changes for both Rows and Columns. Though, in that scenario, maybe
Inkscape just divides the values over Rows and Columns (I still need to make
sure though that users don't need to choose two reference tiles besides the
base tile).

2. Could each render tile in fact be considered more or less like an independent
tile? Like, should we have the option to allows the user to break a tile apart
and drag it around independently? (internally, Inkscape would still keep track
of their row and column value, so users could still use some mechanism to
select a whole row for example)
