Clarify the difference between absolute, relative and scaled

[justalemon]

The code is a bit of a mess, so I need to explain what absolute, relative and scaled means. My current idea is to rename all of the existing properties, fields, parameters and comments to show the following behavior:

• Absolute: The value from Settings > Graphics > Resolution (for example, 1366x768)
• Relative: The float value between 0 and 1
• Scaled: The 1080p based scaled resolution (for example, 1920x1080 for 2560x1440 16:9)
