DragonBones png export quality is quite low

[2blackbar]

Please improve export scaling and filtering, this is test image exported with 200% scale in dragonbones:

First is mesh( most blurry), middle one is nomesh, last one is pasted in photoshop( this is how it should look like ) , image upscaled to 200 by linear interpolation, this kind of quality like on image 3 is not possible in dragonbones especially with mesh which has worst quality, please allow us to use linear interpolation for mesh or bicubic , eventually XBR 2x , sourcecode for these is here : https://github.com/Windblade-GR01/2dimagefilter/releases
Image resizer has a lot of scaling algorithms , please add some of them to dragonbones , currently output quality with mesh is low.Upscaling to 200 with linear interpolation would be good too, currently its bilinear which blurs the images, this is wrong for crisp lines and pixel art/sprites.
Or at least improve meshes export quality so its like middle one, right now its probably bilinear which is one of the worst.
Ability to choose export scaling and mesh filtering algorithms would be great !
Also there is an issue when exporting GIF animation with transparent background, animations has transparent holes in some places, it looks like it was exported on black, then black was removed by magic wand , and some holes were left where it removed too much from actual animation instead of only removing background.
