* Use GLExtension::Has in cold path
* Throw error at first error
* Remove aniso check, all hardware support it. Bonus add GL4.6 extension support
* Remove viewport array check. We replace the function pointer anyway
Allow to compile on distribution that still ship an older file
The file is only a patchup of the missing 4.3/4.4/4.5/4.6 define
v2: rename the file and add khronos copyright
There are 2 extensions GL_ARB_debug_output (promoted from amd extension)
and GL_KHR_debug (the core extension, promoted from GL_ARB_debug_output)
As we use the callback we could drop the manual query of errors.
And save us the load of the GL_ARB_debug_output extension function pointer.
I used glcorearb.h as input file
Code is limited to core gl + KHR/ARB extension
GL1.X must be handled manually (need only 3 functions)
I think the solution would be to migrate gl.h/glext.h to the
single glcorearb.h. However we might need to update the code to fetch
pointer accordingly
Note: we don't check the null ptr anymore on GSwnd. It isn't important
as we check the extension.
v2: update copyright
v3: update copyright space
v4: update copyright of script
fix copyright
This pull request is for the pending reorganization of the folder structure on GSdx,
making it better organized and easier to work with.
Also remove unused GSTextureFX.cpp file.
