From 93d30c3de95a1d373285cd7353343817c23dbb64 Mon Sep 17 00:00:00 2001 From: Eduardo Lima Mitev Date: Tue, 27 Oct 2015 15:18:45 +0100 Subject: [PATCH] mesa: Add QueryInternalFormat to device driver virtual table This new function queries different driver parameters for a particular target and texture format. It is basically a driver hook to support ARB_internalformat_query2. Since ARB_internalformat_query2 introduced several new query parameters over ARB_internalformat_query, having one driver hook for each parameter is no longer feasible. So this is the generic entry-point for calls to glGetInternalFormativ and glGetInternalFormati64v.
