Simply RP - Chat Edit Box Extender (CEBE)

Version 0.021a Changelog:
-- Hotfix for a .lua error when messaging in a zone channel

Version 0.021 Changelog:
-- Cleaned up chat edit box a bit on the visual side of things.
-- Caret (the blinking line when editing text) does not move to fill blank spaces when lines move.

Version 0.020 Changelog:
-- Added support for v.11.2

Version 0.019 Changelog:
-- Fixed an issue where hidden characters/pipes from other addons would contribute to the character count and awkwardly shift the vertical cursor, or give weird line spacings.

Version 0.018 Changelog:
-- Revised an issue where the chat edit box would not expand enough, and expanded or contracted at strange intervals.
-- We used to do this by guessing, but I discovered some API calls that do this for us. It should be MUCH more reliable now.

Version 0.017a Changelog:
-- Hotfixed an issue introduced in the previous update where receiving a whisper would focus the chat edit box even if the user was not typing.
  -- Now, this will only happen if the user had the edit box open when whispered.

Version 0.017 Changelog:
-- Fixed issue where newly opened whisper tab windows would pull the focus away from the edit box.
-- Added an optional 'Character Counter' feature and enabled this by default.
  -- Two numbers will appear, e.g. 100 (1). The 100 in this example is how many characters you've typed. and the (1) denotes how many messages will be sent.
  -- This can be toggled in the Options -> Addons page.

Version 0.016 Changelog:
-- Added support for v.11.1.7

Version 0.015 Changelog:
-- Placed this addon in an addon category

Version 0.014 Changelog:
-- Added support for v.11.1.5

Version 0.013 Changelog:
-- Fixed addon option's page.
-- Added some text to help players understand how to move the chat box.

Version 0.012 Changelog:
-- Added support for v.110100

Version 0.011 Changelog:
-- Fixed a lua error that came after deprecation of some API calls in TWW's prepatch.

Version 0.01 Changelog:
-- Improved how the box expands to accomodate larger messages. Things should be more accurate now!

Version 0.009 Hotfix:
-- Added a 250 message limit to decrease bloat.

Version 0.009 Changelog:
-- Enabled new functionality (old to WoW, but lost with reparenting the chat edit box) where Alt + Up Arrow or Alt + Down Arrow cycles through text history.
-- This addon should store more messages than WoW did natively.
-- This probably needs more optimization, like a message cap-- but I don't expect that anyone will ever notice excessive performance usage from this addon since it hovers in the 20 KB/s - 40 KB/s range. Even if this gets multiplied by 10, no one would have their gameplay impacted.
-- Thank you Lily Ann Silver for the suggestion! ♥

Version 0.008 Changelog:
-- Fixed an issue where text would easily bleed off the frame when typing in long channel names or whispering a target with a long name.

Version 0.007 Changelog:
-- Made the Chat Edit Box have resizable width and improved the ease-of-use with positioning and scaling.
-- Revised the line height calculation so that it is more dynamic and more easily scalable. The frame behind the edit box should work better at containing larger blocks of text. It's still not perfect, but it's better.

Version 0.006 Changelog:
-- After encountering a very, very rare .lua error I made a revision that should, in theory, resolve the issue. More testing is needed, but I'm confident enough in it to post an update. At the worst, this update does nothing. At the best, it fixes a rather egregious error.

Version 0.005 Changelog:
-- Added a configurable Font Size to make the addon more accessible to users. Thank you Lily Ann Silver for the suggestion! ♥
    -- When altered, this will dynamically alter the Character Limit and Line Height variables so that the frame properly stretches.
-- Added a /cebedebug slash command that simply prints your stored variables. Useful for seeing exactly what font size you're using. It'll be easier to adjust exactly to what font size you want in the future, but a slider was easy to implement.

Version 0.004 Changelog:
-- Optimized the script by about 99.80%. We went down from a 10 MB/s memory cost to ~20 KB/s
-- This also resolved the rare c-stack overflow.

Version 0.003 Changelog:
-- Integrated support for WoW Patch 10.2

Version 0.002 Changelog:
-- Moved the chat's default position so it's not hiding under action bars. It IS front and center though-- move it where you want it!
-- Added optional Header that displays "Chat", can be disabled, but it helps move the chat frame where you need it to be!
-- Made the header persistent between sessions.

Version 0.001 Changelog:
-- Addon made!
-- Allows players to type multi-line posts
-- Compatible with Typing Tracker
-- Configurable window opacity
-- Line Break Button that is configurable
-- Small Line Break Button settings
