Clicking on the base facilities in the prefab base does
not always call up the info text for that facility.
Nothing happens for certain facilities. This has to do
with the placement on the grid. Clicking in certain
empty areas of the base grid will call up the
description text for a facility.

I'm currently investigating this.

Seems to be an offset-problem that effects placement of the
images, but not the checking of the mouse-coordinates.

Adding a "+71" to "y" (see below .. the comments are not
from me) helps, but i need to check where and why that is
the case ... especially the fixed value(s) is(are) kinda bad
style.

cl_basemanagement.c line 1401+
=============================
x = ( BASE_SIZE * 326 + ( rowCnt * 186 ) - bvCenterX ) *
bvScale;
y = ( ( rowCnt * 280 ) - bvCenterY ) * bvScale; // 512 - 71
=> 71 pixel overlap
=============================

ok, i've added some debug code, to show the problem (mattn,
this might interest you) just set the "#if 0" to "#if 1" in
"MN_DrawBase"

The problem is that the base-map is drawn from square
images, with a isometric image on it ... the corners are
transparent.

* = building
# = invisible

So the invisible parts are still used for click-actions :(

Possible solutions

* The easiest solution would be to change the base-view to
top-down, but i assume the 3d-models of the buildings are
not designed for that.

* One possible solution would be to provide a click-mask
(basically a black/white image that defines where the
building is (could even be the alhpa-map of the
builing-images) and read from that on mouseclick/mousover
... I dunno how easy that is.

* The most accurate solution would be to display the
building as real-3d, but for that textures (and maybe even
polycount) should be decreaded a bit if performance is going
down. Not to mention the work involved :(

This is fixed with the new baseview
