I want to put relief text on curved surface but can't find way to do that in OpenSCAD. I'm aware it's possible to bend text in Blender and then `import stl`, but I don't like this workflow. I found sort of working solution but it's not perfect.

```
$fn=50;

module bend_text(caption, angle, text_height, text_width, text_depth, steps=10, k=1) {
    dh = text_height / steps;
    r = text_height / (angle * PI / 180);
    h0 = - text_height / 2;
    translate([0, 0, -r])
    rotate([angle / 2, 0, 0])
    for(i=[0:steps-1]) {
        rotate([-i * angle/steps, 0, 0])
        translate([0, -(dh * i + h0), r / k])
        intersection() {
            linear_extrude(text_depth) 
                text(caption, valign="center", halign="center");
            translate([0, dh * i + h0, 0]) 
                cube([text_width, dh, text_width], center=true);
        }
    }
}

bend_text("test", angle=90, text_height=9, text_width=30, text_depth=1, steps=10, k=1.1);

```

Is there better way?
