Computes the DataType/Vector2 dimensions (in pixels) that will be taken up with text when using the specified formatting parameters and size constraints.

Note, the fontSize parameter will not accept the Enum/FontSize Enum. Instead the integer size corresponding with the Enum/FontSize Enum should be used. This is not equal to the value of the Enum/FontSize Enum. For example, for Size11 font, the integer 11 should be used.

This function is a useful alternative to the TextLabel/TextBounds property of the TextLabel and TextButton objects. Using the TextLabel/TextBounds property to calculate the dimensions text requires is often impractical as it requires a TextLabel object to be created.

With GetTextSize, the dimensions required by a particular text string in a particular TextLabel or TextButton can be calculated before any object is created or text property set.

Developers are recommended to add a pixel of padding to the result to ensure no text is cut off.
