Subject: r300g: move the emission of GA_POINT_MINMAX into emit_fb_state
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=74f94e8fdfe035fa68acdc19e6b0afc2957a4264;p=mesa.git

r300g: move the emission of GA_POINT_MINMAX into emit_fb_state

The only practical limits are the ones derived from the currently-set
framebuffer state.
