[LDPatternCreator] Release 1.6.5

[Magnus Forsberg]

Hi Nils,

As a user of both LDPE and LDPC I want to have a more unified keyboard shortcut list.

As a user of LDPC I want to have "F" as a shortcut to flip a pair of connected triangles.
As a user of LDPC I want to "override", or slow down, my Windows scroll wheel speed setting, to finetune the position of a background picture.

As a user of LDPE I want to have 1, 2, 3, 4 on my numpad as shortcuts for Select, Move, Rotate and Scale.
(it looks like it should work, but it doesn't on my laptop. I have to click on the buttons.)
As a user of LDPE I want to have Ctrl+Q as a shortcut to "Merge to nearest edge and split".
As a user of LDPE I want to toggle between overlapping surfaces, like it's possible to do in LDPC by holding down Ctrl-key.

Bug:
It is sometime very hard to attach a new triangle to a vertex in a prim, or grouped set of vertices. e.g.  a common vertex, present in both in a ndis and a disc, is not connectable. But when Fast Triangulation II in activated it's possible.

Bug:
Triangles overlapping and using the vertices in a primitive is undetected by the overlap detector.

Code:

1 11 -3.9 0 1.7 1 0 0 0 1 0 0 0 1 3-4ndis.dat
1 12 -3.9 0 1.7 1 0 0 0 1 0 0 0 1 5-8disc.dat
3 13 -3.1929 0 2.4071 -3.9 0 1.7 -2.9761 0 2.0827
3 14 -2.9 0 2.7 -3.9 0 1.7 0.9 0 1.7
3 10 -3.9 0 2.7 -4.9 0 1.7 -3.9 0 1.7

Bug:
I sometimes get triangles like this one. Looks like some kind of rounding error. The decimal comma is missing.

Code:

3 16 -2900 0 1700 -3900 0 700 -2.181717 0 0.9578202

It should have been: 3 16 -2.9 0 1.7 -3.9 0 .7 -2.181717 0 0.9578202

Bug:
Or like this one:

Code:

3 12 0.9 0 1.7 -2.9 0 1.7 -3.9 0 1.7

It's a colinear triangle
