Rewrote scratchpad function to work more as I envisioned it:
sequential calls will pass on a variable to each other that gets updated with the new offset position in the scratch buffer.

First simple test with scratch memory, just to verify that it works.

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.

Fixes to the time system to make it work on real hardware, and prevent potential crash from division by zero.

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.

Tweaks to time system:
- Init time system first, because it no longer depends on video mode.
- Made real time updates less frequent, so it has less impact on performance. Still more than accurate enough.

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.
