slider holds values with which the sub index extent/3d bounding box is mutliplied by and depending on the map canvas containing the extent or camera being within the scaled bounding box, we render the full sub index or just the overview

This PR adds a slider that controls the point of switching between rendering overview only and rendering a sub index of the VPC.
The slider is more aggressive going to the right, less aggressive going to the left.
On 2D map canvas, if the average extent width of the sub indexes multiplied by the value from the slider is higher than the viewable map canvas, a sub index is loaded, otherwise overview only gets rendered.
Similarly, in the 3D Map, multiplier is applied on the sub index bounding box and if the camera is located within the box, sub index is fully loaded and rendered, if the camera is outside the box, overview only is rendered.
One change is that when all the sub indexes are shown in the 3D Map, we disable overview rendering to save resources.
