Calculate the result of trimming text.
start_offs -- offset into text to treat as screen column 0
end_offs -- offset into text to treat as the end of the line
start_col -- screen column to trim at the left
end_col -- screen column to trim at the right
Returns (start, end, pad_left, pad_right), where:
start -- resulting start offset
end -- resulting end offset
pad_left -- 0 for no pad or 1 for one space to be added
pad_right -- 0 for no pad or 1 for one space to be added

Scale val in the range [0, val_range-1] to an integer in the range
[0, out_range-1]. This implementation uses the "round-half-up" rounding
method.

'7777'
>>> "%x" % int_scale(0x5f, 0x100, 0x10)
