#450046 by TR: Don't report error at admin/reports/status when PHP memory limit set to -1 (Unlimited)

#396930 by drewish: Drop code that's been committed to D7 core and move the rest into core imagetoolkits.

#204497 by Rob Loach: Background color when scaling / cropping. And a fix for transparent backgrounds.

set file permissions to 664 after modification, not 775... 775 is bad. execute is evil unless you're a directory.

#292890 by drewish, Can't call imageapi_get_available_toolkits() at install time... since the module hasn't been installed yet.

tnx...

Call drupal_set_message() rather than dsm() so people without the deve.module don't get fatal errors.

#264006 by drewish, drop tmp files from imagemagick since we added batch processing... imagemagick should save files now.

imageapi_imagemagick.
