Subject: Use tikz to draw biometry.

* ksh-report.el (draw-biometry, make-temp-script, combine-pdfs,
crop-pdf): Delete functions.
(biometry-subfloat, latex-macro): New functions.
(insert-biometry): Use tikz to draw biometry.
(make-report-header): Use subfig and tikz packages. Use calc tikz
library. Define tickheight, parameterheight and parameterageheight
macros.
* biometry.asy: Delete file.
