Re: [libredwg] Improve test suite

[Pero Brbora]

This is "double homework"

Some tests in testsuite/testcases fail because double values are  
compared using == comparison. I have addes compare_double() function  
to testsuite/testcases/common.c add replaces == comparison with a  
function call to compare_double.

This gives me:
# of expected passes 345
# of unexpected failures 11

There are still some errors in reading flags (9 errors in lwpline.c)  
and dwg_ent_endblk_get_dummy (2 errors in endblk.c).
