GridMap Example for Texture #5
Description
Here's another example that is less flexible because both grid dimensions are reducing by 1.0. So, where they overlap will always be -2.0. This means those areas will always be transparent because you can't set easily set opacity to 3.0 to account for this (2.0 is the max).

The above video shows the settings below, with the GridMap scale starting near 10 and moving towards -10. This is logarithmic with 256 pixels as the baseline. So, 256 * 10^10 through 256 * 10^-10. The opacity setting is configured so that 1/2 of the gridmap is transparent and the other 1/2 is opaque, in both X and Y dimensions. This is an attempt to mimic the rough surface of canvas with a pencil-like tool.
