This works nicely. However, the problem is that the "puck" only appears when you use the mouse to scroll up or down. When I try to grab the puck to scroll right, it disappears. We need a stable scrollbar as in most interfaces. This adjustment makes the scrollbars more stable:

{
    "class": "puck_control",
    "layer0.texture": "User/Theme - Default/vertical_white_scrollbar.png",
    "content_margin": [3, 4], //makes horiz scrollbar taller
    // Adjust RGB color. Optional: comment the following line (or set 255,255,255) to not modify image color
    "layer0.tint": [200, 170, 250]
},
{
    "class": "puck_control",
    "attributes": ["horizontal"],
    "content_margin": [3, 4], //makes horiz scrollbar taller
    "layer0.texture": "User/Theme - Default/horizontal_white_scrollbar.png"

}
{
    "class": "tab_label",
    "parents": [{"class": "tab_control", "attributes": ["selected"]}],
    //"fg": [30,30,30],
    "fg": [255,131,0] //change highlighted tab color
}
