Subject: gallium: Add texture usage information to surface_buffer_create
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a41a253ce3b667fc8ad1bfbafce9e3e633667383;p=mesa.git

gallium: Add texture usage information to surface_buffer_create

	We need aditional meta data about the usage of the surface
	in softpipe because we need to be able tell the diffrence
	between PRIMARY and DISPLAY_TARGET surfaces.
