Draw a text

[Wikunia]

Is your feature request related to a problem? Please explain.
It's not really a problem but it would be nice to have something more visual appealing.

Describe the solution you'd like
I would like to have some kind of interesting appearance of text from left to right. Based on #43 it is currently possible to let text of everything else for that matter fade in. Would be awesome to have appear(:draw) or something which only works for text at first and might make sense for everything else later.

Describe alternatives you've considered
Currently there is only the way to fade or scale but it doesn't show that text is from left to right (at least in English 😄 )

Additional context
Can be seen in manim here:

Easier to see with 0.25x speed. It doesn't have to be this animation. A simple one like appearing from left to right using clipping might be a good start.
