Lightweight Java Game Library Code

ARBTextureCompression, GL13: Only allow ByteBuffer for glCompressedTex*Image*D since the spec defines that the image data is interpreted as (unsigned) bytes anyway. Also let the imageSize parameter be automatically determined

Autogen changes from previous commit

Made all GL functions only query ContextCapabilities.getCapabilities() once. Now all GLCheck checks will take the ContextCapabilities instance as an argument instead of querying for it. Inspired by MatthiasM, who just don't seem to be content with LWJGL performance, ever ;)

Removed duplicate functions (based on NVIDIA's glext.h)

Added 21 new extensions:
EXT_bindable_uniform
EXT_draw_buffers2
EXT_draw_instanced
EXT_framebuffer_sRGB
EXT_geometry_shader4
EXT_gpu_shader4
EXT_packed_float
EXT_texture_array
EXT_texture_buffer_object
EXT_texture_compression_latc
EXT_texture_compression_rgtc
EXT_texture_integer
EXT_texture_shared_exponent
NV_depth_buffer_float
NV_fragment_program4
NV_framebuffer_multisample_coverage
NV_geometry_program4
NV_gpu_program4
NV_parameter_buffer_object
NV_transform_feeback
NV_vertex_program4

Added missing CURRENT_RASTER_SECONDARY_COLOR enum value (GL 2.1)
Added EXT_gpu_program_parameters extension

Added EXT_blend_color & EXT_blend_minmax extensions.

ReferencesStack now clears references when popping to avoid keeping buffer references around too long

Added SGIS_generate_mipmap & SGIS_texture_lod extensions
