{.$define DGL_TINY_HEADER}
{
If you enable the define DGL_TINY_HEADER no function automatically will be loaded if you
call ActivateRenderingContext. This may some bit faster and the smart linker can delete
all non used functions. This will reduce the filesize of your binary file. But in this
case you have to load the functions by yourself. There are two ways to do this.
1. You can load whole extension by calling the func Read_Extensionname. But if you do
this it's possible to load functions you dont use. So you have the same "problem"
like before. But it's only an bit smaler.
> Read_GL_ARB_multitexture;
2. You are able to load only the functions you exactly need. In this case you are able
to use the variables of the dglOpenGL.pas. So you only need to load the functions
and you can use the header like before.
To do this you have to created and activated an opengl context and than you can load
the needed functions.
> ActivateRenderingContext(fDC, fRC);
> glActiveTextureARB := dglGetProcAddress('glActiveTextureARB');
> glMultiTexCoord2fARB := dglGetProcAddress('glMultiTexCoord2fARB');
So only the function "glActiveTextureARB" and "glMultiTexCoord2fARB" will be loaded.
Please notice that the extension variables won't be loaded if this define is active. But
you can call dglCheckExtension to check if any extension exists. You can assign them to
the variables of the dglOpenGL.pas so all code they use this will find them.
> GL_ARB_shading_language_100 := dglCheckExtension('GL_ARB_shading_language_100');
