Subject: r200: Fix EXT_fogcoord rendering.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=edad20fff16a719a37a80fd9605a6d8a0383de13;p=mesa.git

r200: Fix EXT_fogcoord rendering.

The fogcoord calue was not pushed to GPU because of implicit float to int conversion.
Fix is to use float pointer to buffer object so no conversion is done in assigment
