Proper way of rotating glyphs

[Василий Троцкий]

Hi evryone!

Now i am using FreeType library to fill texture atlas with font glyphs in order 
to render strings as a sprites with texture from atlas.
Then i want to add glyph rotation(and scaling) effects. But let's just talk 
about rotation now.
 
Should i just apply this transformations to my textured sprites(quads, pair of 
triangles...etc) OR rotate glyphs in "font coordinate system" using FreeyType's 
FT_Glyph_Transform()/FT_Set_Transform() then get transformed glyph bitmap using 
FT_Load_Char() with FT_LOAD_RENDER flag or FT_Glyph_To_Bitmap(), upload this 
rotated glyph bitmap to texture atlas and then render the sprite?

Confusing quote from freetype doc  
https://freetype.org/freetype2/docs/tutorial/step1.html

>Rotation usually disables hinting.

So, hinting is disabled, right?
Are there any image quality advantages expected then? May be i really should 
just rotate my sprite and don't bother?
