benjamin rouveyrol c3ddf156d3 Fix for HDR toggling on some platforms. ...

This does not truly change HDR since these platforms do not support toggling this at runtime. Instead we change the swapchain to be in SDR, and we end up in SDR mode with HDR output mode.

SDR in HDR mode is slightly darker on the TV, more than when comparing the screenshots of the swapchain. This is most likely due to the TV response, which needs to be investigated later on to see if we can somehow match the 2 properly.

In addition to the 2 CLs from main, this CL allows BP to change the CVar r.HDR.EnableHDROutput . On these platforms, the CVar is set with ECVF_SetByCode as soon as HDR was supported and calling EnableHDRDisplayOutput with ECVF_SetByGameSetting would get ignored

Slate: Clear the uncached draw elements and the batches elements once they are rendered. We do this to remove hard references to the Glyph Sequence from the previous frame. Cached draw elements are still cached. An old Glyph Sequence may still be a reference in a cached element but it is the responsibility of the SWidget to do the proper invalidation. Deprecated the FSlateRenderer::GetDrawBuffer to remind the user to call FSlateRenderer::ReleaseDrawBuffer.
