Wrong extension checking

[BoyBaykiller]

I was trying to run the precompiled binary contained in bin_x86_64_windows. Output:

I don't exactly know how hasARBTextureFilterAnisotropic is set here:

AnotherCraft/ac/client/application.d

Line 107 in daa527a

enforce(hasARBTextureFilterAnisotropic, "The graphics card does not support ARB_texture_filter_anisotropic");

I do know though that my GPU not only supports OpenGL 4.6 (where anisotropic filtering is core) it also has GL_ARB_texture_filter_anisotropic and GL_EXT_texture_filter_anisotropic.

This project is quite old so if you're not willing to work on it anymore I understand that. If you do, here is what I would suggest:

According to the OpenGL Wiki the correct way to check for a core extensions is to both check for the version which is 4.6 and the presence of the extension which would be GL_ARB_texture_filter_anisotropic. Since GL_EXT_texture_filter_anisotropic is considered to be a ubiquitous extension it would make sense to also check for that - and then use the
corresponding functionality provided by that extension.

I'm keeping this open in case someone fixes it in the code or something :)
