TextBox revamp please

I want the features that @boatbomber implemented in his TextBox Plus module to be native to Roblox TextBoxes:

Also TextLabels should have font size relative scaling (for the same reasons basically the rest of Roblox UI supports scaling). Otherwise w/o any extra scripting, either the font will be too small/too big on some devices or if we enable .TextScaled then the font size will vary depending on the length of the input eg:
RobloxPlayerBeta_pDMZZXrEL8 RobloxPlayerBeta_88sHNxwqzI
UITextSizeConstraint is of no use here.
