keepAspect slider range change

keepAspect on/off button

nuiPushMenu("Tools");
nuiPushToolBox("Transform");
nuiToolBoxItem("@VidResize",VidResize());
nuiPopToolBox();
nuiPopMenu();
nuxDefExprToggle("VidResize.keepAspect");


change to .h (since button returns 0 or 1)

  ...

  Select1 = Select(keepAspect+1, Resize1, SetBGColor1, 0, 0);

NTCS/PAL radio buttons (assumes on, on.focus, off, off.focus)

...
nuxDefRadioBtnControl("VidResize.vidFormat", 1, 1, 0,
  "0|ux/vr_ntsc",

to create your own radio buttons

    copy the following to your startup directory:
      doc/html/cook/macros/radiobutton.h 
      doc/html/cook/macros.relief.h 

    type
      shake -radio "NTSC size" 79 vr_ntsc $HOME/nreal/icons/ux -t 1-4 -v

    (creates 4 buttons, each of which says "NTSC size")



Pop-Up Menus

...
nuxDefMultiChoice("VidResize.vidFormat", "NTSC|PAL");


change logic in .h 

if (vidFormat=="NTSC"){
  yRes=486;
}
else {
  yRes=576;
}

or

curve int yRes = vidFormat=="NTSC" ? 486 : 576;

(only allows for 2 options)
