Is there an LCD mode which does not grow the image size?
No. You need three colour channels for LCD rendering.
What is the format of the bitmap memory when FT_PIXEL_MODE_LCD is in
place? The docs say 8-bit, but it being 3x as wide suggests maybe 1
byte for each color component?
I see FT_RENDER_MODE_LCD and LCD_V which both indicate that they
produce larger-than-normal bitmaps. I tried FT_RENDER_MODE_LCD and
of course the text glyphs were all 3 times as wide (as the docs
indicate). Am I supposed to then shrink them back down?
No, you are supposed to apply a colour filter.
What would the pseudo code be for that? I tried calling
FT_Library_SetLcdFilter, but the resultant image is still 3x as wide.
Is the idea that the color filter samples bytes from the bitmap and
results in a new bitmap which is the original width?
Is there some other call I need to make to enable the color filter?
