* get everything running on windows * get all tests passing on jruby * for jruby, consider adding kind of a back-door method, e.g. gets_as_jruby_bufferedimage that allows internal calls to pass scanlines along natively. Something similar might slightly speed up the C extension as well by eliminating some memory copies. * have a setting where decode / encode warnings will result in exceptions * add #initialize_copy * Check frozen status on setters, etc. * Check frozen status (and freeze) on all VALUEs that we stash for later use * Check trusted status (1.9.x only)
