Layers: Non-standard blend modes for layers with shader and FBO-based workarounds

    XMLWordPrintable

Details

    Description

      Not convinced the 3DS1 implementation is functional and correct. To begin with, it seems it only supports fullscreen layers. See QT3DS-657.

      Rather, let's implement a working solution for the new runtime.

      Some of the bits needed for this (compositor refactoring) also provide enablers for implementing post-processing effects later on.

          • P1: Critical - Urgent and Important, will STOP the release if matched with set FixVersion field. This includes regressions from the last version that are not edge cases; Data loss; Build issues; All but the most unlikely crashes/lockups/hanging; Serious usability issues and embarrassing bugs & Bugs critical to a deliverable. This is the highest possible priority for requirements.
