	@SYMTestCaseID

	GRAPHICS-FNTSTORE-0028

	@SYMTestCaseDesc

	Tests all bitmap fonts. 

	@SYMTestActions

	1. Creates a CFontStoreFile object from a file placed in ROM.

	2. Copies the file from the Z-drive to the C-drive.

	3. Tries to load the file from the C-drive to create a CFontStoreFile object.

	4. Opens two read streams. One for the old file and one for the new file.

	5. Retrieves the sizes of the files and checks they are the same.

	6. For both files it tries to create a font and allocates memory for them.

	7. Character metrics are compared between the two files.	

	@SYMTestExpectedResults

	Test should pass
