Do we need the LV_ATTRIBUTE_MEM_ALIGN attribute here as well?

Good question, but I think it's not required.

Mis-aligned memories caused an issue when they were passed to a periphery (such as DMA) which expected aligned memory. The glyphs are processed byte-by-byte (or even bit-by-bit) in the library and never passed to hardware.

@kisvegabor Thanks for the clarification!
