New option: Screenshot Resolution

[Jerozgen]

I suggest you to make new option: "Screenshot Quality".
It increases screenshot resolution to make quality screenshots.

The screenshot size should be limited to something like 4x to avoid crashing due to not enough memory.
For example:

• 1x = 1680 x 1050 (screen size)
• 2x = 3360 x 2100 (4K)
• 3x = 5040 x 3150
• 4x = 6720 x 4200

The 4x screenshot seems to work with the default memory limit of 1GB.
When running on a 4K monitor, the 4x screenshot may need more memory.

I suggest you to add the warning massage about this to the description of Screenshot Quality.
