Pre-failing test for color interpolation during rendering. (#2001) 
Before #1996, this failed with:

image_test.go:1997: At(1, 0): got: {64 64 128 255}, want: {0 128 128 255}

The difference is:

- Before, colors were interpolated in straight-color space:
  - Background: {0 0 255 255}
  - Vertex A: {255 0 0 0}
  - Vertex B: {0 255 0 255}
  - Interpolated: {128 128 0 128}
  - Premultiplied: {64 64 0 128}
  - Onto Background: {64 64 128 255}
- After, colors are interpolated in premultiplied space:
  - Background: {0 0 255 255}
  - Vertex A: {255 0 0 0}
  - Vertex A premultiplied: {0 0 0 0}
  - Vertex B: {0 255 0 255}
  - Vertex B premultiplied: {0 255 0 255}
  - Interpolated: {0 128 0 128}
  - Onto Background: {0 128 128 255}

This DIFFERS from the sample fragment shader, which returns the color as is
(Kage allows vertex color values to be used for arbitrary purposes and
interpolates independently):

- Shader sample:
  - Background: {0 0 255 255}
  - Vertex A: {255 0 0 0}
  - Vertex B: {0 255 0 255}
  - Interpolated: {128 128 0 128}
  - Onto Background: {128 128 128 255}

as the blend function is `GL_ONE` / `GL_ONE_MINUS_SRC_ALPHA`. This shader behavior
is unchanged but has been documented by #1996.

Negative mipmaps tend to allocate extremely big images.

Instead, encourage to use images with explicit padding when enlarging
