2021-08-25	LibGL: Implement `glFogfv`	Jesse Buhagiar
	This currently just sets the fog colour in the rasterizer.
2021-08-14	LibGL: Implement glVertexPointer	Stephan Unverwerth

2021-08-12	LibGL: Turn Sampler2D into an actual class	Stephan Unverwerth
	This extracts the sampler functionality into its own class. Beginning with OpenGL 3 samplers are actual objects, separate from textures. It makes sense to do this already as it also cleans up code organization quite a bit.
2021-05-31	LibGL: Implement basic texture units	Jesse Buhagiar
	These are merely a way to hold the different texture target bind points that a texture can be bound to.
2021-05-30	LibGL: Introduce Texture base class for all texture types	Stephan Unverwerth

2021-05-26	LibGL: Implement Texture State Management	Jesse Buhagiar
	Some very primitive Texture State management. Data can now be uploaded to textures.
2021-05-26	LibGL: Add Texture Name Allocation	Jesse Buhagiar
	Texture names can now be allocated via `glGenTextures` and deallocated via `glDeleteTextures`.
2021-05-16	LibGL: Implement glShadeModel()	Stephan Unverwerth
	This turns off interpolation of vertex colors when GL_FLAT is selected.
2021-05-16	LibGL: Add defines and stubs for glBlendFunc()	Stephan Unverwerth

2021-05-11	LibGL: Implement glGenLists and a few friends	Ali Mohammad Pur
	This commit implements glGenLists(), glNewList(), glDeleteLists(), and glCallList(). The 'compiled' records are implemented as a vector of member function pointers and tuples containing their arguments, and a mechanism is implemented to allow the recorded calls to copy-capture values from the time of the call; this is currently only used with glLoadMatrix.
2021-05-09	LibGL: Add depth buffer class	Stephan Unverwerth

2021-05-08	LibGL: Move polygon clipping to `Clipper` class	Jesse Buhagiar
	This code has also been optimised to be much more memory friendly by removing a _lot_ of extraneous copies. The result is that, when profiled, it's around 8x faster than the previous implementation. Co-Authored-By: Ali Mohammad Pur <ali.mpfard@gmail.com>
2021-05-08	LibGL: Add software rasterizer	Stephan Unverwerth
	This is based mostly on Fabian "ryg" Giesen's 2011 blog series "A trip through the Graphics Pipeline" and Scratchapixel's "Rasterization: a Practical Implementation". The rasterizer processes triangles in grid aligned 16x16 pixel blocks, calculates barycentric coordinates and edge derivatives and interpolates bilinearly across each block. This will theoretically allow for better utilization of modern processor features such as SMT and SIMD, as opposed to a classic scanline based triangle rasterizer. This serves as a starting point to get something on the screen. In the future we might look into properly pipelining the main loop to make the rasterizer more flexible, enabling us to enable/disable certain features at the block rather than the pixel level.
2021-05-08	LibGL: Implement a basic OpenGL 1.x compatible library	Jesse Buhagiar
	This currently (obviously) doesn't support any actual 3D hardware, hence all calls are done via software rendering. Note that any modern constructs such as shaders are unsupported, as this driver only implements Fixed Function Pipeline functionality. The library is split into a base GLContext interface and a software based renderer implementation of said interface. The global glXXX functions serve as an OpenGL compatible c-style interface to the currently bound context instance. Co-authored-by: Stephan Unverwerth <s.unverwerth@gmx.de>
