Numeric values for OSM

[sy2002]

From a Skype discussion between @sho3string and @MJoergen:

So this core has vertical / horizontal center for the vga out display.

Currently, the display is shifted to the right hand side on my crt. this is no problem as I can hard code some value to shift it across to the left for now.

wire [4:0] HOFFS = ... some value from OSD ( 0 - 31 )
wire [2:0] VOFFS = ... some value from OSD ( 0 - 7 )

This then gets fed into HVGEN ( i guess horizontal/vertical video generator ?? ) which moves the image back to the left depending on the values above.

Now I can easily add a sub menu like this below. But it's not very intuitive and uses up much real estate.

Horizontal Offset

1
2
4
8
16

Is it possible to some day implement something like this where you can use the arrow and automatically count up values from a minimum value to a max value ? You could say this is a feature request. I think this is more intuitive and we won't need any submenu for that at all.

Horizontal Offset - <0 -31>
Vertical Offset - <0 - 7>
