Weston launcher renders icons incorrectly depending on size and screen rotation
The weston launcher will incorrectly render icons depending on whether the output it is on is rotated and depending on what size the provided icons are. Attached are a series of screenshots which demonstrate permutations of (a) whether firefox or xfce4-terminal is the first [launcher] section, (b) whether the display the launcher is rendered on is rotated or not, (c) whether 32x32 or 128x128 icons are provided, (d) whether the launcher is on the top of the screen or the left.

The working permutations are only the non-rotated permutations using 32x32 icons at the top of the screen. All other permutations have some sort of rendering error.

I tried launching weston-terminal --font="..." with several monospace fonts such as "DejaVu Sans Mon" and "Noto Sans Mono" without any improvement.
