Use buf_height and buf_width in Matrix.draw() (#903)

Browse Source 
## What are the changes about?

buf_height is declared at the start of the draw() function of the
Matrix animation but both buf_height and self.terminal_buffer.height are
used in the function. replace every occurence of
self.terminal_buffer.height by buf_height for consistency.

The same goes for buf_width and self.terminal_buffer.width.

no functionnal changes

## What existing issue does this resolve?

N/A

## Pre-requisites

- [x] I have tested & confirmed the changes work locally
