Feature: allow multiple PatchMap instances for distinct canvas rendering #106
Description
Describe the problem
There is an issue where only one patchmap instance can be used at a time. It is not possible to create and use multiple patchmap instances.
Describe the proposed solution
The desire is to create multiple patchmap instances to draw separate display elements on individual canvases.
In other words, the goal is to display multiple canvases on one screen, where each can operate and perform tasks independently.
