Expected Behavior

OBS recognize that the resource has ben modified.
If the resource is delated clear it.
Try to load the new image. Can be fail if it is currently writed.
If ok update the resource, if it fails leave the previous image.

Current Behavior

OBS recognize that the resource has ben modified.
Clear the image.
Try to load the new image.
If it fails, you don't show the image.

Steps to Reproduce

1. Add Image Source (like a png file)
2. Fast update the image (like 2-3 times per second)
3. You will notice that sometime the resource disappear (because it fail to load it)
4. You have to refresh the image so OBS can notice it and try to reload else it stay cleared

Anything else we should know?

I have fix it on my computer, but I'm not familiar with GitHub and I prefer someone revised it.
I have reduce the check time from 1 sec to 0.5 sec (image_source_tick).
I have created a function only for update modified content image_source_modified.
Load the resource in memory and if it loaded ok copy in the current resource else destroy it.

Start by reviewing the image_source_tick and image_source_modified functions, then reproduce the issue by updating a PNG two or three times per second on Windows 10. Use the linked OBS log for context. Done means a failed reload keeps the previous image visible, while a successful reload updates it and a deleted resource is cleared.
