Avoid a double memory copy during bindTexture
If a painter is active on a QPixmap being uploaded, it will be copied
twice, first to create a QImage and then from QImage into a texture.
The first copy is unnecessary since the QImage is only temporary, so
we can force it to be created as a reference instead of a copy.
