Description
Upon loading textures from data, we do extra data copy:
subresDesc.setData(QByteArray(ptr, size));
We should reduce the data copies to reduce CPU loading.
Loading textures from memory happens in many cases:
- most of camera implementations
- most of screen and window capture implementations
- software decoding
- disabled hw texture conversion.
