- Areas with same tabs are put in a column/row automtically. Move preferred size constraint from Area to the column/row. This avoids a "spring" effect of the quadratic solver if multiple Areas are in the same column/row. - Replace GetString by ToString. - some clean up git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40941 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add an alternative solver to lp_solve. The solver based on Ingo's active set solver but is able to handle arbitrary hard and soft constraints. The advantage to lp_solve is that the active set solver can optimize variable in respect to a quadratic objective function. This makes it possible to minimise the quadratic derivation to a desired value e.g. \Sum_i(x_i - x_{i,pref})^2 -> min. The solver part has been refactored in this way that both solver can be used with the same layout specifications. The active set solver is default now; the performance is not as good as lp_solve, though. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40285 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added libalm.so and its dependency liblinprog.so. libalm.so provides a BLayout implementation (BALMLayout) using the Auckland Layout Model (ALM). The original ALM was implemented by Christof Lutteroth, the Haiku/C++ version by James Kim. The code needs some review, but the test programs seem to work fine. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23889 a95241bf-73f2-0310-859d-f6bbb57e9c96
