| Setting text on multiple layers issue |

Hellois.
I'm on a mission to make an 'text atlass or sprite' ish plugin which will make the number of input characters to the power of two; combination 'sprite image'.
At the moment the code can generate one image atlass with n combinations. As a image has a limited combination spaces it will later add images as needed to make all the combinations over multiple images. But first i must understand how to set text which i hope someone would help out with.
What im struggling with is applying text. Im not able to set text on multiple layers. No matter what i do it seems like the ..WriteToCanvas() funciton only sets text to the original background layer. I'm unable to make a new layer and apply text to it.
The function ..SetAndAnchorText() is where you would modify the code to help me out if possible, or give me some good pointer as i'm been struggling for a few days to many. 
Starting point:
The code works and can produce an image so you can see what i mean by atlass/sprite. Create a new 256x256 RGB_Image and run the plugin to se results. Then make a new same image and add the letter i to the end of .."Text for atlass" of the plugin. The expected result should be a whole image with text combinations in stride of two and the second should be roughly half the image with text. At the moment the code creates and error instead.
Code:
#!/usr/bin/env python
from gimpfu import *
from math import *
from time import sleep
def WriteToCanvas(image, drawable, x, y, text):
return pdb.gimp_text_fontname(
image, # IMAGE image The image
drawable, # DRAWABLE drawable The affected drawable: (-1 for a new text layer)
x, # FLOAT x The x coordinate for the left of the text bounding box
y, # FLOAT y The y coordinate for the top of the text bounding box
text, # STRING text The text to generate
-1, # INT32 border The size of the border: -1 <= border
False, # INT32 antialias Antialiasing (TRUE or FALSE)
26, # FLOAT size The size of text in either pixels or points
0, # INT32 size_type The units of specified size: PIXELS (0) or POINTS (1)
'Monospace') # STRING fontname The fontname (conforming to the X Logical Font Description Conventions)
# returns stride of 3 for characters that use kerning

kerning += [src[idx1-1]] + src[idx1+1:idx2].split(',')
src = src.replace(src[idx1:idx2+1], '', 1)
idx1 = idx2 = 0
return kerning + [src]

Hey guys! I use gimp on occasion but definately an amateur at it. Im currently paying a gal to take seamless images I find on vector stock, put them together then to a certain size, with the pattern on the image being around 1" in areas. Im terrible at explaining so here's another explanation: Take said image, tile it, then scale it down. I can't for the life of me figure out how to tile an image on gimp 2.8 (only version I have). Ive googled several times but it always wants me to create my own tile image, which isn't what im trying to to. any help would be great appreciated!

| Problem with drawing tablets |

I have had a minor problem with drawing tablets for some time - it is not a showstopper.
When I open GIMP the pen is greyed out in Configure input devices. If I then open Libreoffice Draw and do a scribble, close Draw without saving, the pen works correctly. It is no longer greyed out in input devices. It is as though GIMP is failing to load something which Draw then loads.
This has occurred in Ubuntu 20.04 and 18.04, in GIMP 28 as well as previous versions.
For me this is only a minor irritation but a solution may help others.
