There were no problems with the build but I currently get a blank screen when I try to load an SVG.\r\n\r\nAt first every time I loaded an SVG the program would panic with `version 130 is not supported`.  I tried switching to `#version 140` since that's what the glium examples use and sure enough, no more crashes.\r\n\r\nWhat I have now is:\r\n\r\n* App window flashes white at startup, then turns black.\r\n* Clicking the black window opens a file picker.\r\n* I choose `tiger.svg` from the repository.\r\n* App window turns white, and the terminal logs 5 identical messages about pan and zoom.\r\n\r\nI'm not sure if the shaders need to be updated to support version 140, or if the bug lies elsewhere.  I'm not super familiar with graphics programming so any thoughts would be appreciated."},"comment":{"url":"https://api.github.com/repos/maps4print/azul/issues/comments/404220304","html_url":"https://github.com/maps4print/azul/issues/5#issuecomment-404220304","issue_url":"https://api.github.com/repos/maps4print/azul/issues/5","id":404220304,"node_id":"MDEyOklzc3VlQ29tbWVudDQwNDIyMDMwNA==","user":{"login":"whmountains","id":8680147,"node_id":"MDQ6VXNlcjg2ODAxNDc=","avatar_url":"https://avatars3.githubusercontent.com/u/8680147?v=4","gravatar_id":"","url":"https://api.github.com/users/whmountains","html_url":"https://github.com/whmountains","followers_url":"https://api.github.com/users/whmountains/followers","following_url":"https://api.github.com/users/whmountains/following{/other_user}","gists_url":"https://api.github.com/users/whmountains/gists{/gist_id}","starred_url":"https://api.github.com/users/whmountains/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/whmountains/subscriptions","organizations_url":"https://api.github.com/users/whmountains/orgs","repos_url":"https://api.github.com/users/whmountains/repos","events_url":"https://api.github.com/users/whmountains/events{/privacy}","received_events_url":"https://api.github.com/users/whmountains/received_events","type":"User","site_admin":false},"created_at":"2018-07-11T15:53:02Z","updated_at":"2018-07-11T15:53:02Z","author_association":"NONE","body":"Just opened #7 which seems to cleanly fix the problem.  Unfortunately I still don't know the root cause, but it most be somehow related to difference between the code that runs in the `'window_loop` and the code that runs in the `do_first_redraw` function.\r\n\r\nIf you'd like me to run some more tests to get to the bottom of this just let me know."}}
