Subject: Allow redeclarations to override the type of a variable
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgl.git;a=commitdiff_plain;h=ec5ec4201b60b8ba15aaa6208e453225a1d7a291;hp=e55f79ccb21e8c1be3d86f127e3ec1583e58ce92

Allow redeclarations to override the type of a variable

This can be used to e.g. change the sampler type of the diffuse map.  At
the moment the appropriate sampling function also needs to be overridden
since texcoord dimensions are not handled automatically.
