skewScore in scandata is corrupt

[raj]

We think the code in the scribe image loop that writes skewScore to scandata.xml is writing bad data.

Example in item socialismvscivil00bras

The skewScore of leaf 272 has a > in it:

    <page leafNum="272">
      <handSide>LEFT</handSide>
      <pageType>Normal</pageType>
      <addToAccessFormats>true</addToAccessFormats>
      <rotateDegree>-90</rotateDegree>

      <skewAngle>-0.25</skewAngle>
      <skewAngleDetect>-0.25</skewAngleDetect>
      <skewScore>&gt;3.06</skewScore>
      <skewActive>true</skewActive>
      <origWidth>2912</origWidth>
      <origHeight>4368</origHeight>

      <cropBox>
        <x>987</x>
        <y>1198</y>
        <w>1814</w>
        <h>2718</h>
      </cropBox>
      <ppi/>

      <pageNumber>246</pageNumber>
    </page>

Here's another example of bad scandata that may have the same cause.

For some fields, these are now flagged during ProcessJP2 - see redrow category "ProcessJP2 bad scandata (non-numeric rotation)." This one is from book universalantholo01garn, which shows "Rotation e>90 is not numeric" in its log. Here's the scandata for the page (the bad element is rotateDegree):

<page leafNum="379">
  <handSide>RIGHT</handSide>
  <pageType>Normal</pageType>
  <addToAccessFormats>true</addToAccessFormats>
  <rotateDegree>e>90</rotateDegree>
  <skewAngle>0.55</skewAngle>
  <skewAngleDetect>0.55</skewAngleDetect>
  <skewScore>3.76</skewScore>
  <skewActive>true</skewActive>
  <origWidth>2912</origWidth>
  <origHeight>4368</origHeight>
  <cropBox>
    <x>137</x>
    <y>357</y>
    <w>2304</w>
    <h>3556</h>
  </cropBox>
  <ppi/>
  <pageNumber>361</pageNumber>
</page>

Another case of bad scandata. This is a scribe2 book scanned in January, without compress-in-the-field.

from the scandata for leaf number 388:

  <rotateDegree>-9</rotateDegree>

(This one wasn't flagged as bad scandata; it redrowed because the missing final 0 caused the image to be mis-rotated by roughly 90 degrees, which led to a failed crop operation, as the crop box didn't fit with the image turned sideways.)
