this pull request introduces a togglable "X-Ray Mode" to the View menu. it allows for soft, semi-transparent rendering of the mesh.

changes:

• added xray toggle to the view menu and initial properties in wings_view.erl.

• updated render_objects/4 in wings_render.erl to apply gl:blendFunc and gl:blendColor when the xray property is true, bypassing the depth mask for a soft transparency effect.

To me this looks annoyingly bad without edges drawn and more complex thing then a cube,
should we only support it with edges and in workmode?

depthMask off is a pain to render nicely we have the same problem with transparent materials,
you can only do so much without a ray-tracer or sorting all faces.

But I can see that it is useful sometimes.

Users will want to be able set the color, but nice default color, Preferences/Advanced maybe ?

you have a good point about that.
i never thought about other side effects that it may brings, but i was using 'Art of Illusion' 3d software that has this feature. it helped me so much when i have many objects and dense sides.

i think supporting it only in certain ways like edges would not be bad, as it also simplify it more.

for alpha color, i picked this from 'AoI' program, it is nice one, but users are free to choose from preferences if they want.

maybe also add option that sets alpha level? like [ 25% - 50% - 75% ], i think we are giving wings so much freedom here haha.

thanks for your efforts nonetheless :)

This option would be useful for modelling with reference. I usually set a transparent material and have to use workmode to see through the object or switch to wireframe only.

@dgud , maybe it could look at the Show Edges option. This way, if some user wants to get the x-ray without edges it could just toggle the edges visibility - good for everyone. 🙂

@Crosshair97 I think it can free for user to choose. Just like other parameters in the Preference dialog. You could add an option to set the colour as well.
