DColorPalette:SetNumRows
Description
Roughly sets the number of colors that can be picked by the user. If the DColorPalette is exactly 6 rows tall, this function will set the number of colors shown per row in the palette.
DColorPalette:Reset or DColorPalette:ResetSavedColors must be called after this function to apply changes.
Arguments
Example
Creates four DColorPalettes, each with a varying number of colors per row.

frame:SetSize( 350, 350 )
frame:SetTitle( "SetNumRows Demonstration" )
frame:Center()
frame:MakePopup()
local label = vgui.Create( "DLabel", frame ) -- Create the help text
label:Dock( TOP )
label:SetText( "Difference between SetNumRows( 4 ), SetNumRows( 8 ), SetNumRows( 16 ) and SetNumRows( 24 )" )
label:SetWrap( true ) -- Enables text wrapping for lower resolutions
label:SetAutoStretchVertical( true ) -- Needed for the text to show properly
local pallette1 = vgui.Create( "DColorPalette", frame ) -- First DColorPalette with 4 colors per row
pallette1:SetPos( 4, 60 )
pallette1:SetNumRows( 4 )
pallette1:SetSize( 40, 60 )
pallette1:Reset()
local pallette2 = vgui.Create( "DColorPalette", frame ) -- Second DColorPalette with 8 colors per row
