Added support for setting the clear color to a generic sky color.
This is very basic and it does exacerbate the gaps between polygons on some maps, but at least we get to have something of a sky.

Fixed frustum calculation and implemented point and sphere tests. Now also tested and looking decent.

Made some tweaks after experimenting with interlaced mode:
- VSync needs to be enabled for interlaced mode to work at all
- Y offset does not need to be doubled in interlaced mode

Small tweaks:
- Math functions return results in 32-bit int, cast back to short is done only where necessary
- Changed GTE screen distance to obtain an exact 90 degree horizontal FOV in 4:3 mode

Debugging work:
- Load map data using a macro, so I can easily change the implementation for all data chunks.
- Implemented a visdata function that loads all 1's, so that every leaf will be drawn.
- Point-to-plane distance now uses copies of input vectors. May or may not be faster.
- Fixed fps counter rounding and disabled vsync so we can see the true framerate

Adjusted display values slightly to better match aspect between NTSC and PAL, and for better vertical centering in PAL.

Set up some helper functions for memory management, including scratchpad memory. Moved the primitive buffer here too.
This will probably have to become inline functions or macros at some point, but for now it's just pure C.

Modified triangle rendering code so that it finally works on real hardware.
Not sure why the original method doesn't work, probably some weird limitation on the memory/GTE register subsystems.
This will get rewritten anyway so it doesn't matter much now.

Made a few changes to the ordering of the display code, which fixes execution on real hardware.
This also fixes the text overlay, which now renders on top of the 3D content.

Adapted Select button input to switch between NTSC and PAL, which is a bit more useful at the moment.

First implementation of interlaced mode and switching display modes by pressing Select.
Still a bit buggy, not sure what I'm doing wrong. Will have to revisit this after performance is improved.

Expanded display initialization code with proper handling of both NTSC and PAL aspect ratios, and allowing PAL to render at higher resolution.
Also includes provisioning for switching between progressive and interlaced modes.
