These changes speed up how long it takes to populate the GameGrid after
clicking on a dat in the Tree. MAME 0.155 dat was used for testing.
Before the changes population times were
windows .net = 2.75 seconds
linux mono = 23 seconds
After the changes, both now take 300-400ms.
This was done using 2 main changes.
1. Fully move populating the rows' Values to the CellFormatting function
2. Determine the total number of rows we will need and use
GameGrid.rowCount to set the row count to that. This is much faster
then doing individual Add()'s for each row.
- on initial rendering mono likes to send a resize event where the width
is 0, ignore it. This was causing gbDatInfo to not render until a
manual resize was done.
- set AutoScaleMode to System.Windows.Forms.AutoScaleMode.None. This
fixes a number of rendering issues under mono and didnt seem to have any
negative effect under c#/windows builds.
- tweak some of the initial form sizes and locations on FrmMain. A
number of the setting didnt make sense based on the size of the panel
they were put it. This resolves an issue with the gbDatInfo and
gbSetInfo starting off with the wrong size under mono.
