Yes, this is normal because LCD rendering requires padding to deal
with color fringes. This used to be the case only with
FT_CONFIG_OPTION_SUBPIXEL_RENDERING defined. Otherwise the LCD target
was actually grayscale without padding.  Since 2.8.1, the LCD target
is always optimized for LCD and, therefore, padded.
