This can be a size_t, avoids the cast in the callback function.

The ul_ prefix is redundant as destruct is already named to make it clear this deals with underline data.

Since this is getting more involved than a pair of numbers, more readable to make this into a struct.

eg:

struct UnderlineData {
    /** The offset of the character to test. */
    int str_test_offset;
    /* The underline with in pixels. */
    int char_width_px;
    /** Write the X,Y offset here. */
    int r_offset_px[2];  
};
