[fpc-devel] CreateGrayScalePalette exception

[Paul Ishenin]

Hello,  FPC developers' list.

CreateGrayScalePalette raises an exception. The problem is that palette 
is created with count = 0 and every color assigment increase color 
count. I dont know why it is done so but as result you cannot assign 
palette colors from highier indexes to lower. It is not a big problem 
but CreateGrayScalePalette doesnot follow this rule and raises an exception.

Attached patch fixes CreateGrayScalePalette.
