Title text component options for nicer text about audio-visualizer-python HOT 3 CLOSED

In addition to text borders, it'd also be nice to be able to define the text border width.

Other suggestions for improving the text component:
Give a "center" option, that keeps the text centered in the screen (based on the canvas size)

from audio-visualizer-python.

The text component should also re-calculate it's position on a canvas size change. We had discussed before about storing the position as a float and always calculate the pixel positions based on simple math at render time.

xPosition = x / width     |    x = width * xPosition
yPosition = y / height    |    y = height * yPosition

If current Canvas size is 1280x720, and text position is 640x374:

0.5 = 640 / 1280
0.519444444 = 374 / 720

If resolution chagned to 1920x1080:

960 = 1920 * 0.5
560.99999952 = 1080 * 0.519444444

And round to the closest whole pixel:
x = 960 y = 561 <- equivalent positions for 1920x1080
