Imager 0.63

This release primarily contains changes to improve ease of use - rather than you having to convert images to the appropriate number of channels, Imager handles it internally. How to handle drawing colors and the default combine mode is a thornier problem left for some other release.

the font libraries are now only initialized when needed.
moved the imtoc.perl code into Imager::Preprocess
paste() and rubthrough() now adapt the source image data to the destination, so you can now safely paste/rubthrough from greyscale images to color images or back, or from alpha channel images to noalpha channels or back.
rubthrough() now falls back to pasting when the source doesn't have an alpha channel. This effectively treats the source as having a max alpha channel, the right thing to do.
re-worked most of the area filling code to use a common set of functions when filling. Corrected normal combine mode. Rewrote most of the combine modes to match the way the SVG draft defines them with respect to a translucent source and destination. Added tests for translucent source and destination. Added tests to check 8-bit/sample and double/sample combines work similarly.
writing a 2 or 4 channel image to a JPEG file will now write that image as if composited against a background, black by default, overridable with the i_background tag/parameter.
writing a 2 or 4 channel image to a PGM/PPM file will now write that image as if composited against a background, black by default, overridable with the i_background tag/parameter.
writing a 2 or 4 channel image to a BMP file will now write that image as if composited against a background, black by default, overridable with the i_background tag/parameter.
