Import issues when using MGCB

[zephyrusgreene]

Description

I noticed the following issues on the ported tutorial Riemer's Flight Sim.

• The .bmp file used for section 2 does not draw correctly when imported using .bmp importer. Renaming the file to .png tricks MGCB into using a different importer, which correctly reads the renamed .bmp file.

• The xwing.x file initially used for section 5 lacks normals or is losing them on import and crashes at mesh.Draw(). Using the technique "ColoredNoShading" resolves basic drawing for that section. Section 6 starts using lighting, bringing the issue right back. Could also be an import issue, unknown.

** Update on the .x file: converting .x to .fbx and then in blender -> resetting normals + shade smooth or shade flat resolves whatever data was causing parameter errors.

Steps to Reproduce

Use Monogame 3.8.1 and MGCB for imports.
Copy the code from Riemer's 3D Flight Sim tutorial Section 2.
Build and run.

Expected Behavior

2D Texture should draw as is.

Actual Behavior

2D texture used for vertex texture drawing is shifted leftward with the overflow on the right side.
