Bug 303065 – [RenderStyleGen] Add initial support generating parts of RenderStyle

• Status: RESOLVED
• Resolution: FIXED
• Component: CSS

[Sam Weinig]

Add initial support generating parts of RenderStyle, including the generation of a few test properties.

This will be done in stages:

Stage 1: Add initial support in the generator for getter and setter function implementations and enable it for a few properties.  Function declarations remain hand written.
Stage 2: Enable for remaining non-special cased property getter and setter function implementations. Function declarations remain hand written.
Stage 3: Generate the function declarations for the already generated getter and setter function implementations.
Stage 4: Generate initial value functions.
Stage 5: Remove as many special cases as practical.

[Sam Weinig]

I didn't mention it above, but the point of leaving the function declarations hand written initially is that we use them to ensure the implementations have the correct signatures, validating the work.
