Hide Cursor While Typing

### Description

It would be lovely if the mouse cursor could disappear when typing. This is an issue for people who require large cursor sizes.

### Use case/motivation

When I start to type, the mouse/cursor image should vanish preventing me from typing until I am under my mouse and unable to see what I type. This is an issue for people who require large cursor sizes.

No file, test, or entry point is named in the issue. Start by locating NetBeans' mouse-cursor and text-input handling, then determine the platform-specific behavior needed to hide the cursor while typing. Done means the cursor is not visible during typing for users with large cursor settings and returns appropriately afterward.
