hi,
I'm a noob in coding and want to learn how to code. So if someone does have some time, can you answer my questions, please:

"RS_Text is derived from RS_EntityContainer. You can define a virtual function draw() in RS_Text then."

If RS_Text is derived from RS_EntityContainer, shouldn't the draw() function beeing implemented in the RS_EntityContainer class? (cause using virtual??)

"For zooming, please note we have a model space (as entity sizes are), and a screen(GUI) space as controlled by zooming factor. draw() methods must do the conversion."

What is the model space and the screen space?
model space: the canvas, where drwing is performed??
screen space: the GUI?? so one can zoom the GUI??
