      Description

      Using D3D9Ex was originally done for RT-23704 but was subsequently disabled for RT-30352.

      Benefits of doing this are:

      1) Having persistent textures will help solve the Canvas OOM problem when the surface is lost. See RT-23312.

      2) We can avoid the per-frame overhead of reading back the texture for each Canvas node. See RT-23074.

      3) We can possibly use this to accelerate transparent rendering in the future (although this is unconfirmed). See RT-17510.


      The following problems will need to be resolved before it can be re-enabled:

      1) There were rendering problems when the surface was lost. See RT-27121.

      2) There was a significant performance hit for certain cases of updating textures. See RT-27508.

      3) It was never fully debugged for 3D (no bug ID).
