Image is compressed even when quality is set to 100

[anth0]

I'm expecting to get the full original picture when importing with quality set to 100. However I get a highly compressed image in return (~500KB compressed vs ~7MB original).

This is because of the compression done in GMGridViewController when writing the image to file:
// setting compression to a low value (high compression) impact performance, but not actual img quality if ( ![ UIImageJPEGRepresentation(imageToDisplay, 0.2f) writeToFile:filePath atomically:YES ] ) { return; }

To me the comment is not true as any compression affects image quality. It might not be much but artefacts can be visible upon compression which is not what I expect.

The correct code is commented out a few lines above but I don't know why. Could someone explain? Otherwise I can suggest a PR to use the quality option given as input as the compression rate.
