WebGL1 使用 gl.LUMINANCE 报错，from https://github.com/antvis/L7/blob/beta/packages/layers/src/raster/models/raster.ts#L97

createTexture2D({
    data: new Float32Array(data),
    width,
    height,
    /**
     * WebGL1 allow the combination of gl.LUMINANCE & gl.FLOAT with OES_texture_float
     */
    format: queryVerdorInfo() === 'WebGL1' ? gl.LUMINANCE : gl.RED,
    type: gl.FLOAT,
    alignment: 1,
 });
