Incorrect rendering of image/interpolated heatmap in 3D

[ffreyer]

Same issue as #2889, but with image/interpolated heatmaps. This does not get solved by #2959.

 f, a, p = image(-2..2, -1..1, rand(100, 100); axis = (; type = LScene))

With interpolation we need to apply an image to a rectangle mesh. This works fine in Cairo as long as no perspective projection is present. If perspective projection is included we can no longer encode the transformation in a CairoMatrix (a 2x3 matrix which can include translation, scaling, rotation and sheering).

This is effectively the same problem as we have with textured meshes and lighting in CairoMakie. (Is there no issue for this?) The solution will probably to either support #1880 better or, more likely, to write a small CPU rasterizer for meshes.
