Virtua Tennis 2 graphical issues

[Senryoku]

This game has many issues.

Graphical:

• Flickering during the "Hitmaker" intro
• error: [zgpu] Validation: Texture copy range (origin: [Origin3D x:0, y:448, z:10], copySize: [Extent3D width:640, height:64, depthOrArrayLayers:1]) touches outside of [Texture] mip level 0 size ([Extent3D width:64, height:64, depthOrArrayLayers:512]). While [Failed to format error: "calling %s.WriteTexture(%s, (%s bytes), %s, %s)"]
• Blank screen intro (direct write to framebuffer?)
• Crash during demo (Invalid u_size for vq_compressed mip mapped texture)
• Flickering during replays
• Player shadows are broken Fixed by ce18ce7

zgpu validation error is due to a bogus stride texture (silenced in fca2897):

error(renderer): Texture U size (640) is greater than the allocated size (8)
  TEXT_CONTROL:    holly.TEXT_CONTROL{ .stride = 20, ._r0 = 0, .bank_bit = 0, ._r1 = 0, .index_endian_reg = 0, .code_book_endian_reg = 0, ._r2 = 0 }
  TSP Instruction: holly.TSPInstructionWord{ .texture_v_size = 3, .texture_u_size = 0, .texture_shading_instruction = holly.TextureShadingInstruction.Modulate, .mipmap_d_adjust = 6, .supersample_texture = 0, .filter_mode = 0, .clamp_uv = 2, .flip_uv = 1, .ignore_texture_alpha = 0, .use_alpha = 0, .color_clamp = 0, .fog_control = holly.FogControl.Vertex, .dst_select = 0, .src_select = 1, .dst_alpha_instr = holly.AlphaInstruction.One, .src_alpha_instr = holly.AlphaInstruction.Zero }

Also crashes at the end of a match, probably because of the Bump Map:

error(renderer): Unsupported pixel format holly.TexturePixelFormat.BumpMap
