Arbitrary Colors

[sammy-ette]

The vpoke command allows a user to set any arbitrary value at any address of VRAM.
This also means, since our VRAM is currently just a backbuffer to the SDL texture used as a screen, a user can vpoke a part of that screen to use any colors they want.

This is bad, since Pinwheel is supposed to be a fantasy computer, limited to a 64 color palette, and while I do want that palette to be customizable, it means if a user is dedicated they can have their program using all colors of the spectrum.

A way to fix this is use an SDL Palette

But it can only be used on a surface, which means I'll have to create a texture from the surface every frame
