EnergyGlass — server drawing test

Phase 0. Checks whether this server can draw the glass and door diagrams.

Run these three, in order

1. /info	What this server is, and whether the drawing library loads at all.
2. /draw	The real test. You must see a picture with readable text on it.
3. /stress?n=200	Draws 200 times. Checks for leaks and slowness.

What "pass" means

/draw shows shapes and the words 800 mm, 450 mm and Clear Tempered 12mm. Shapes without text is a fail — the real diagrams need dimension labels.

Send the whole page of /info and /stress, plus a screenshot of /draw.
