13a2138022 GridLayout: Don't divide the max cell size by the colspan or rowspan
Otherwise we end up contraining the layout too much.
The result is still wrong, but probably better. (see #42)

096f55e365 Change behavior of percent sice within the layout
So that size with percentages don't affect the maximum/minimum size

Fixes #117

57d3a34996 Prospective fix for doc errors
In the nightly it appears that `no_mangle` is now considered "unsafe",
so we need to allow that in the ffi modules. For the layout code this
patch also creates that ffi module with prefixed function names, like in
the other modules and only allows unsafe in there.

2ce672bd68 Reduce dependencies
Use only specific lyon packages instead of pulling all of them in.
This slightly speeds up compilation as well as for example lyon_tesselation
doesn't need to be compiled anymore.

fd3c8bf9fa Simplify path event iteration code
* Always apply a transformation (less variants)
* Let the path data iterator take ownership of the data. That will
  make it possible to return a PathDataIterator from a function in the
  future

0f10202ff0 Partially implement row/colspans via cell distribution
This patch distributes the constraints evenly to the occupied cells.
That is not entirely correct, but it's an improvement for the appearance
of the todo app.

56d763cdcf Implement GridLayout using stretch's FlexBox implementation
Unfortunately nesting the boxes to model a grid does't seem to quite
work, so this approach simply creates two boxes for each direction --
similar to the existing algorithm.

7976a4057f Improve handling of nested layouts
We support directly nested layouts, but we did not support indirect
nesting:

    GridLayout {
        Rectangle {
            l2 := GridLayout { ... }
        }
    }

This patch fixes that by detecting this scenario and merging the layout
info of the element (Rectangle) and the layout inside (l2). This makes
it much easier to create re-usable components that use layouts
themselves and allows placing them in layouts.

4054402418 Fix layout info calculation for grid layouts
When the spacing was zero, the constraints would always be zero due to
accidental multiplication with the accumulated spacing widths/heights.
That was meant to be an addition.

* Remove Lyon from the name and instead call it PathDataIterator.
* Remove the fit() function and just provide two factory functions.
