Dia hex-grid vs. triangular grid

[Felix Shvaiger <fshvaige cisco com>]

Hi All,

Hex-grid is great idea (I see it in v0.94) !

As evolution of it, I think,
triangular grid should be added or even
hex-grid should be replaced with triangular.
Triangular grid has all features and advantages of hex-grid
(in fact, tri-grid is exactly hex-grid with extra point in center of hexagon)
and some additional: guidelines are continuous,
more guided directions from each grid point, etc.

Could someone make it for Dia, please ?
