修复3个问题

  1. canvas 填充时允许设置颜色的值为 rgb(200,200,200) 之类的值
ctx.setStrokeStyle('#fff')
ctx.setFillStyle('rgb(179,179,179)')
  1. canvas 填充时允许设置颜色的值为一个渐变 (wx.canvasGradient)
const gradient = ctx.createLinearGradient(0, 50, 0, 210)
gradient.addColorStop(0.5, 'rgba(0,0,0,0)')
gradient.addColorStop(1, 'rgba(0,0,0,0.4)')

ctx.setFillStyle(gradient)
ctx.fillRect(0, 50, canvasWidth, 210)
  1. canvas drawImage() 方法不支持 9 个参数以外的异构 (还支持3/5个参数)
