[Lazarus] A few questions

[Xiangrong Fang]

Hi Mattias,

1) About Laz on Ubuntu 12.04:  it is quite OK, except that the installing
process is still very tricky and after install it has 2 minor problems:

- on first start, it always complains that FPC source is not found.
- on program termination (if run within the IDE), the attached error is
shown.

2) About the bug I reported. I confirm that it does NOT appear on Ubuntu,
but only Windows. And it appears on both Win7 and WinXP, both laz v0.9.30.4
and the bleeding edge nightly build.

3) I used the correct form of FloodFill, now the compiler is happy, but
there is no flood fill at all (both on windows and linux).  btw, to make
sure I use it correctly, I just need to specify a point within the shape I
want to fill, right?
