OpenGL preview grid very distracting

[Bicyclops]

Hello

The cyan grid in the OpenGL preview is very fat and very distracting. How can I change the color to something less distracting, and change the line thickness to 1px?

I compiled hugin-0-7-0-rc6-3749-f00195a91d45, it's still the same.

This is still an issue in today's code.

This can't be changed easily and would require a complete rewrite of the grid code.
But you can disable the grid.

Background: The grid is OpenGL texture with a fixed size which is remapped to the corresponding projection. If we reduce the line thickness in the texture the grid will be not visible for a wide fov (e.g. 360 deg HFOV). So the thickness was optimized for wider fov which is more often used then very small fov as your screenshot.
