Message : Refactoring: Split TextureTest to multiple classes This removes the cube map setup and the draw scale parameter from the tests that don't need them, and reuses the code for setting up the window and the shader program for most of the texture tests. The tests are now structured as follows: TexCoordDrawTest: Test class that sets up a shader program for drawing with texture coordinates. Vertex shader source can be overridden in subclasses, and fragment shader source must be specified in subclasses. Texture2DTest: Inherits TexCoordDrawTest, sets up a 2D texture and a shader for drawing from it. Texture2DTestWithDrawScale: Inherits Texture2DTest, adding a scale parameter that scales the quad that gets drawn. TextureCubeTest: Inherits TexCoordDrawTest, sets up a cube map and a 2D texture and a shader for drawing from them. Texture2DArrayTestES3: Inherits TexCoordDrawTest. Reserves a texture ID and sets up an ESSL3 shader for drawing from a 2D texture array. Also add a few comments about where things being tested are specified. Also, ANGLETest::drawQuad parameter names are renamed to make their meaning clearer. The parameters affect the vertex shader attribute values, which the shader may use for other things besides setting the vertex position.
