Trilobytes MZ: Gradient Text Extensions

RPG Maker MZ provides you with some powerful options for controlling your font and text size, but...don't you sometimes think it's not quite colourful enough? Well Trilobytes has you covered, because now you can add gradients to text!

Please note that due to the character-by-character nature of how the message window works, this isn't applicable to messages or the drawTextEx function. It's mainly for plugins which use drawn text.

If I can figure out a good way to incorporate it into messages I will add this functionality in a later update. Suggestions to that end are welcome.

Features
- Draw text with gradients
- Supports options for drop shadows, bolded text, outline gradients, angle, and more!
- Adds a lineSpacing property for finer control over space between characters
- Control opacity of text, drop shadow and outline separately

Current version
1.12
