{vfx,vfxsd,sd1,sd132}.lay: Regenerate with updated button size and multi-page marks.

[cbrunschen]

VFX family buttons are actually 15.8mm wide, not 15mm. Regenerated all four layouts.

Before:

Real VFX-SD:

After:

The difference is quite small, especially if you look at the groups of buttons on the right side of the panel.

But if you look at the space between the Seq and 0 buttons below the screen, the "After" picture looks a lot more like the real VFX-SD than the "Before" picture.

Now that there is that little bit of extra space beside/between the labels above the buttons, added the double lines above the labels of those buttons that lead to multiple pages of functionality:

Regenerated with improved vertical label placement:

• there's a bit of space between the top of the button and the label above it
• multi-line labels have less vertical space between them

Positions and sizes of labels and Multi-page markers has been recalculated based on metrics from the "Arimo" fonts, which are metric compatible with Helvetica, Arial and Liberation Sans, and should hopefully look reasonable across MAME's supported platforms.

The pseudo-logo text ("VFX", "VFX-SD", "SD-1", "3 2 V O I C E" and "ensoniq" has also been positioned and sized to fill the appropriate vertical space, and likewise, stretched (using align="3") to fill the space horizontally.
