Subject: mesa/main: conversion from float in GetUniformi64v requires rounding to nearest
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1356b422847dfa92dcae1e2709879daa27110795;p=mesa.git

mesa/main: conversion from float in GetUniformi64v requires rounding to nearest

As we do for all other cases of float/double conversions to integers.

v2: use round() instead of IROUND() macros (Iago)
