/**
 * Creates an op that draws a sub-rectangle of a texture. The passed color is modulated by the
 * texture's color. 'srcRect' specifies the rectangle of the texture to draw. 'dstRect' specifies
 * the rectangle to draw in local coords which will be transformed by 'viewMatrix' to be in device
 * space. 'viewMatrix' must be affine. If GrAAType is kCoverage then AA is applied to the edges
 * indicated by GrQuadAAFlags. Otherwise, GrQuadAAFlags is ignored.
