Basic question

[Cesar Crusius]

I have this basic question that can be stupid. Anyway: I want to
render a text at various zoom settings. What is the best way to keep
updating bitmaps?

1) Load glyphs
2) Set character size & load bitmaps
3) Zoom changes, delete bitmaps and return to 2

or

1) Set character size
2) Load glyphs
3) Load bitmamps
4) Zoom changes, delete everything and return to 1

My problem is that I think but I'm not sure that I only need to load
glyphs once for truetype and type1 fonts, and after that I can change
resolutions as many times as I want before getting bitmaps. Am I
right?
