Error: No matching overload for function 'textureLod' found

When running Servo on Android, the following shader compile error occurs (after applying the previous two Android patches, #626 and #627):

D/RustAndroidGlueStdouterr(22216): DEBUG:webrender::device: compile "ps_rectangle"
D/RustAndroidGlueStdouterr(22216): DEBUG:webrender::device: compile "ps_rectangle"
D/RustAndroidGlueStdouterr(22216): Failed to compile shader: "ps_rectangle"

D/RustAndroidGlueStdouterr(22216): ERROR:servo: -- Shader compile failed - exiting --

Here's the textureLod call. The problem occurs on an Odroid XU3, running Android 4.4.4.

That's interesting - as far as I can see textureLod is part of es3. @kvark We could change this to a texture(Offset) right? (even if just as a workaround for now).

Oh, I think we just need to pass 0.0 for the LOD (instead of 0), since it's a float parameter on all overloads of this function. @mmatyas would you be able to confirm if this is the right fix?

[glennw]

Ah, that makes sense.

Thanks; at the moment I don't have the Odroid at hand, but I will try it tomorrow (GMT+1).

Using 0.0 fixed the problem, thanks!
