crash when setting a rgba with integer alpha value (e.g. 0 or 1)

[Former user]

I am not a regex expert, but it seems to be fixed with adding a questionmark in line 94:

pattern = /^rgba\((\d{1,3}),[ ]?(\d{1,3}),[ ]?(\d{1,3}),[ ]?(\d?.\d{1,2})\)$/;

to

pattern = /^rgba\((\d{1,3}),[ ]?(\d{1,3}),[ ]?(\d{1,3}),[ ]?(\d?.?\d{1,2})\)$/;
