float parsing from rgb(), rgba().

[rendarz]

I was thinking to add a feature for the rgb(), rgba() format: float parsing.
For instance: : rgba(1.0f 0.0f 0.0f 1.0f)
That's perfectly compatible with current format, and pretty useful in some circumstances.
I was thinking to add this by modifying the function parse_percent_or_255 to parse_percent_or_255_or_float.
If you're ok with this, I will proceed to code it.
Cheers!

From https://developer.mozilla.org/en-US/docs/Web/CSS/color_value/rgb#values

rgb(R, G, B[, A])
R (red), G (green), and B (blue) can be either <number>s or <percentage>s, where the number 255 corresponds to 100%.

And from https://developer.mozilla.org/en-US/docs/Web/CSS/number

The <number> CSS data type represents a number, being either an integer or a number with a fractional component.

But number in the range [0, 255] can have a fractional component to. So how do we know if a number is in the range [0, 255] or in the range [0, 1] ?

[rendarz]

Simple, with 'f' after the number, they are in [0,1] range, otherwise they are in [0,255] range.
For instance: rgb(0.5, 0.5, 0.5) [0,255] range, while rgb(0.5f 0.5f 0.5f) in [0,1] range.

But this solution won't be compatible with CSS standard you mentioned. So maybe it's better to avoid that.
