Found edge cases with custom qtables
...
And there was a lingering bug since the previous qtable unsigned char fix
(#1814 ) since the call to array.array was in another place, the roundtrip was no
longer equivalent.
That was a minor change, but the revised test wouldn't pass because saving an image
with one custom qtable automatically adds a second to it by the call to
jpeg_set_defaults.
With 1 or >2 custom tables, there is extra work we have to do due to that call.

4) Don't define strcasecmp if you're not even going to use it.
5) Don't include Windows.h with undefs for compilers newer than
1998 everywhere.
6) Don't surpress warnings for MSVC++ 4.0. People still using

Rewrite of the ImagingDrawWideLine function
...
The previous version of the function didn't generate correct wide lines
of even width.
The most notable changes are:
* Make variable names far more descriptive about the process.
* Corrected the width calculation; we should deduct one pixel from the
width because the pixels at the center of the line doesn't count for
the triangles.
* Now we calculate *two* ratios, one for left/top displacement (dxmin)
and one for right/bottom (dxmax), this fix the behavior with lines
of even width.
It can probably be optimized.

Rewrite of the polygon_generic function
...
The (previously refactored) polygon_generic function didn't draw
consistent polygons (equilateral polygons were not equilateral nor
symmetrical).
The most notable changes are:
* The horizontal edges are searched for when finding the polygon
boundaries, drawn and discarded from the edge list used to detect
intersections.
* The intersections are now checked and calculated from the current value
of the scan line (ymin) instead of in the middle (ymin + 0.5).
* Because the change in the scan line behavior, we should duplicate
the intersections in the maximum Y value of an edge or there will be
draw errors with concave and complex polygons.
* The rounds of the X coordinates in the hline function calls are
switched to draw the inner pixels.
* Removed the ugly micro-optimization of qsort at the end.
This implementation of the scan line algorithm may not be technically
correct, it's not optimized and it have problems with some edge cases,
like a wide line from (x0, y) to (x1, y + 1), therefore it should be
reviewed in the future.

Implementation of rounds around zero
...
The rounds used in the library are towards positive/negative infinity.
Since we're in a cartesian plane, rounds around zero are much more
convenient, so we can use positive and negative values with consistent
results.

Refactored polygon functions to unify logic
...
The functions `polygon8`, `polygon32` and `polygon32rgba` all have exactly
the same logic in code, only changes the hline function called inside.
Now all the logic is contained in `polygon_generic` which gets a
function pointer to the hline handler, so there is no duplicated code
anymore.
