Description
Subpixel rendering means to triple the horizontal resolution by rendering on Red, Green and Blue channel instead of pixel level. It takes advantage of the position of physical color channels of each pixel. It results in higher quality letter anti-aliasing.
This would be highly useful on smaller TFTs such as FeatherWing TFTs.

Research direction
Start by reviewing the related LVGL discussion linked in the issue to understand the proposed subpixel-rendering approach and TFT constraints. Done means implementing and validating higher-quality RGB-channel text rendering for the supported TFT displays, but the issue does not identify files, tests, or an entry point.
