Hi There,
es2gears should provide the default precision statement for float. In
our trunk for mesa-demos, this statement is masked. Even if this is one
simple patch, it is needed because the default precision statement for
float is really one "must" point in the spec.
In the ES shading language spec 4.5.3: Hence for float, floating point
vector and matrix variable declarations, either the declaration must
include a precision qualifier or the default float precision must have
been previously declared. So the the default precision statement for
float is a "must" here.
