[Gnash-commit] [bug #26329] Drawing API bug

[Nutchanon Wetchasit]

Follow-up Comment #11, bug #26329 (project gnash):

This problem is still reproducible on current Gnash git version, @bwy's
test file (file #18005) is still showing a filled triangle. @strk's patch
(file #18379) doesn't seem to apply on current codebase anymore.

I have made another test SWF file (using libming's makeswf) which tries to
re-demonstate this problem on both object filling and stroking, and also
include point-based `MovieClip.hitTest()` checks on the resulting shape.

This is a correct result from Adobe Flash Player:

You'd see that the code rendered as a filled star with two unconnected
border lines, and all point-based `MovieClip.hitTest()` checks on the shape
are all passing.

You'd see that the code rendered as a filled pentagon with star-shaped hole
instead, and two lines drawn are also closed in loop. Point-based
`MovieClip.hitTest()` checks on the shape are also mostly failing.

Test SWF, source code, build script, screenshots, and logs are attached as
`linereset-star.zip`.
