Steps to reproduce

get spleen 12x24, .otf install it set WT to use it text_rendering there is a right drop shadow. in the screenshot you see how notepad, visual studio, notepad++, gitk and paint.net render the text using the same font. I tried changing atlas on/off, sw render on/off, system-wide font smoothing on/off (but never cleartype) By the way, using vector fonts on raster devices was and always be a mistake. At least until we reach... I dunno... 600dpi? Maybe 300? Right now for desktop monitors we are looking at ~180 for a 24" 4k monitor. But I digress.

Expected Behavior

Text to be rendered without shadow.

Actual Behavior

Text is rendered with shadow. For what it's worth, the little preview window does show this shadow. Yes, I know this sounds minor, but... I consider text rendering to be quite important.

Contributor guide

Research direction
Investigate the font rendering pipeline in the atlas engine, focusing on how the Spleen font's glyphs are rendered. Check the antialiasing settings and ensure no shadow effect is applied.
