Closes flutter/flutter#147259.

Changes:

  • Make sure the default of kNearest is used consistently
  • Partial revert of [Impeller] Remove MipFilter::kNone redux #40491, re-adding kBase
  • Added some documentation about relevant enums, and why the default is kNearest
  • Wired up kBase in the Metal, Vulkan, and OpenGLES backends

Expecting an update to the dart_ui_filter_quality_none golden file:

@chinmaygarde to confirm, I think I remember this being weird because I had to fake support no mips.

I suspect we still need to treat an unspecified param as kBase here

looks good to me

// TODO(https://github.com/flutter/flutter/issues/148253):
// `MipFilter::kNearest` is the default value for mip filters, as it
// cooresponds with the framework's `FilterQuality.low`. If we ever change the
// default filter quality, we should update this function to match.
sampler_desc.mip_filter = MipFilter::kNearest;

Its probably correct for this to be changed to base since we don't generate mipmaps for glyph atlas (as they glyphs are generated at exact scales)
