Whether it has a glide failed callback?

[jiansheliuxing]

When I use gilde, i always use a placeholder image resouce. So gilde will set the placeholder into the target imageview at first. When glide load image failed, the target imageview will show the placeholder image.

When I use GlidePalette, the onPaletteLoaded(Palette palette) just only called when the glide loaded the image successfully. if load image failed, it won't callback.
I think it's better to add a callback when glide load image failed. Then I can use my default palette color just like placeholder image.

forget my poor English...
