A new background rendering approach is used for smooth fonts which almost eliminates flicker. tft.print... can now be used with a background rendered for smooth fonts. Font_Demo_1/2/3... examples have been updated. A new "docs" folder has been created and files moved there. The Tools folder now only contains support tools. #1757 fixed by using Arduino calls. A new USER_SETUP_ID parameter can be added to setup files and checked via a new verifySetupID(id); function. Version raised to v2.4.50
