18 | Support for ConsoleControl protocol. Support for UGA Draw spliter.\r | |
19 | Support for DevNull Console Out. This console uses memory buffers\r | |
20 | to represnt the console. It allows a console to start very early and\r | |
21 | when a new console is added it is synced up with the current console\r | |
