| Summary | 0031597: Visualization, TKOpenGl - allow disabling Alpha component writes within OpenGl_Context::ColorMask() |
| Description | Current implementation of OpenGl_Context::ColorMask() property allows enabling/disabling writes into all color components at once.
This is enough for most scenarios, however in some cases it is desired disabling writes into Alpha color component individually - to prevent unexpected blending of render target flushed by external compositor. This happens, for example, in case of WebGL canvas, and cannot be trivially disabled by canvas flags. |
