DARNIT_RENDER_LOGIC_OP

Used with d_render_logic_op to wrap glLogicOp.

typedef enum {
        DARNIT_RENDER_LOGIC_OP_NONE     = 0,
        DARNIT_RENDER_LOGIC_OP_AND      = 1,
        DARNIT_RENDER_LOGIC_OP_NAND     = 2,
        DARNIT_RENDER_LOGIC_OP_OR       = 3,
        DARNIT_RENDER_LOGIC_OP_NOR      = 4,
        DARNIT_RENDER_LOGIC_OP_XOR      = 5,
} DARNIT_RENDER_LOGIC_OP;

DARNIT_RENDER_SCALE

Used with d_render_tilesheet_scale_algorithm to change how a tilesheet is interpolated if it's stretched when rendered. Default is DARNIT_SCALE_NEAREST.

typedef enum {
        DARNIT_SCALE_NEAREST            = 1,
        DARNIT_SCALE_LINEAR             = 2,
} DARNIT_RENDER_SCALE;
