            Bug ID: 279586
           Summary: [TextureMapper] Add precision hint to
                    samplerExternalOES
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Platform
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jani at igalia.com

Some Android emulator versions fail on rendering because glShaderSource in TextureMapperShaderProgram fails with 0x505 GL_OUT_OF_MEMORY.
It turns out that Android emulator OpenGL ES implementation doesn't implicitly define any precision to samplerExternalOES.
Adding precision hint to samplerExternalOES across all platforms is harmless because OpenGL ES implementation is not
required to use hint information. This is needed for WPEView/Android.
