Reject text files resembling TGA images Fixes issue #295 The imlib2 TGA loader returns an imlib image handle without any actual data when given a text file like this: T Content-Type: application/javascript Content-Length: 3836 Last-Modified: Wed, 23 Sep 2015 12:25:47 GMT Etag: "56029a4b-efc" Expires: Sat, 20 Aug 2016 15:14:33 GMT Cache-Control: max-age=604800, public Accept-Ranges: bytes Fortunately, `imlib_image_get_data()` returns NULL in this case, so that we can use it as an additional check when opening files. 2017-11-23 13:35:32 +00:00			`VERSION = git-20171123`

Much more portable Makefile The config.mk file is now optional and only needs to be created if one wants to persistently overwrite default macro values. Features used in the Makefile that are not yet in the POSIX standard: - Advanced macro assignment operators '+=' and '?=' [1] - Special target .PHONY [2] - Pattern rules [3]; only needed when $srcdir != '.'. For every pattern rule there is an inference rule with the same effect. Hopefully, the inference rules get picked up by make programs not supporting pattern rules. - Silently including multiple possibly not exisiting files [4] [5] [1] http://austingroupbugs.net/view.php?id=330 [2] http://austingroupbugs.net/view.php?id=523 [3] http://austingroupbugs.net/view.php?id=513 [4] http://austingroupbugs.net/view.php?id=333 [5] http://austingroupbugs.net/view.php?id=518 2017-10-12 08:56:03 +00:00			`srcdir = .`
