- FT_Set_Char_Size if m_resolution is set (> 0) - `FT_Set_Char_Size` if m_resolution is set (> 0)
- FT_Set_Pixel_Sizes, divided by 64, if m_resolution is not set (= 0) - `FT_Set_Pixel_Sizes`, divided by 64, if m_resolution is not set (= 0)
The method height() returns m_height / 64; The method height() returns m_height / 64;
