Lukas Stockner d8f550875b Fix #124038: Performance issue with color sampling in 3D Viewport
The issue here is that copying the GPU viewport back to the CPU is an expensive
operation, so doing it for every frame when dragging the eyedropper is not ideal.

Instead, copy it once at the start and keep reading from it until the user
releases the eyedropper.
