Controls automatic texture coordinate generation for rendering sprite points. +If PIPE_CAP_TGSI_TEXCOORD is false: When bit k in the sprite_coord_enable bitfield is set, then generic input k to the fragment shader will get an automatically computed texture coordinate. +If PIPE_CAP_TGSI_TEXCOORD is true: +The bitfield refers to inputs with TEXCOORD semantic instead of generic inputs. + The texture coordinate will be of the form (s, t, 0, 1) where s varies from 0 to 1 from left to right while t varies from 0 to 1 according to the state of 'sprite_coord_mode' (see below). |
