Manuel Stoeckl a23cdbbea1 Add 'output render_bit_depth [8|10]' command
This makes it possible to hint to the renderer and backends how many
bits per channel the buffers that the compositor draws windows onto
should have. Renderers and backends may deviate from this if they
do not support the formats with higher bit depth.
