Meter background images wrong for BBC and EBU meter types

[Richard Lamont]

Version 0.4.1-3 amd64

The background images are wrong for the BBC and EBU meter types. Instead of one image it appears to be three squashed-up images side by side in the same area. It appears to be OK for the VU and DIN types. I haven't checked the correlation meter types.

The problem seems to be caused by the compressed PNGs used. Comparing the file sizes with the developer's source:

Using the larger PNG files fixes the problem. I don't know whether it's a bug in the compression used, or a bug in jmeters.
