---------------------------------------------------
resource imagestringbox ( resource image, int font,
int top, int left, int bottom, int right,
int align, int leading, string text, int color )
---------------------------------------------------
This function allows you to draw text inside a box.
It will automatically wrap at the end of the line.
It also supports cutting off text if it goes
outside the box. Align methods supported are left,
center, and right. Manual new lines can be made by
using \n (note that you can not escape that symbol
though). If you're wondering, leading is the space
between lines. An important note is that it will
RETURN the resource - it will not directly modify
the resource provided. An example is provided
below.
