* Panels with backdrop filters are batched now and reuse the same frame grab, break batch on Z groups Before: https://files.facepunch.com/matt/1b0311b1/sbox_HB6vN6Reo6.png After: https://files.facepunch.com/matt/1b0311b1/sbox_gFO4enjxiv.png * Save backdropGrabActive, panel children can't share a backdrop (if they use one) since they won't contain the fresh quad, but siblings can use the same backdrop still Fixes overlapping blurred panels using the original frame grab e.g Sandbox: Before: https://files.facepunch.com/matt/1b0311b1/sbox_M8xXVyxcsF.png After: https://files.facepunch.com/matt/1b0311b1/sbox_RePJDF3HWW.png (Even though Sandbox shouldn't be layering 3 blurred panels on top of each other)
