A lazy way to wrap strings in dragonruby.

render_text.rb

# This breaks when the characters no longer fit on the line.  A smarter version would iterate using word/line boundaries
# Sample Usage: 
#   rect = args.layout.rect(row: 3, col: 12, w: 6, h: 7, dx: 0, dy: 0) # OBJECTIVE
#   text = "OBJECTIVE:\n\nMECHs are threatening\nour CITIZENS:\n+ Bring the CITIZENS home.\n+ Destroy the MECHs."
#   render_text(args, args.outputs.primitives, rect, text, 1, "/fonts/PixeloidSans.ttf")
#

  y_offset = 0

  i = 0

  while i < len
    x_len = args.gtk.calcstringbox(work + text[i], font_size, font).x

    if (x_len >= rect.w || text[i] == "\n")
      pipeline << {
        x: rect.x + x_offset, y: (rect.y + rect.h) - y_offset,

      work = text[i]
      y_offset += font_h
    else
      work += text[i]
    end
