effect of having cached glyphs.

ii. Load sample data from config file, specified by aSampleDataKey.

iii. Create RFbsGlyphMetricsArray, open on sample data.

iv. For each repetition, call RFbsGlyphMetricsArray::Get(), adjusting font at each repetition.

v. Measure time from from first to last repetition.

Measures the performance of querying the TOpenFontCharMetrics using the different

are compared against each other, using the same fonts, and same sample data.

This test uses glyphs that have not been rasterized before, therefore for certain

APIs this will mean rasterizing the glyphs.

@SYMTestActions

i. Load sample text data from config file.

ii. For each of RFbsGlyphMetricsArray, RFbsGlyphDataIterator, and CFont::GetCharacterData():

	1. Create 50 new fonts.

	2. Run the test, calling the necessary API once per font/loop.

	3. For GetCharacterData() and RFbsGlyphDataIterator(), cycle through each glyph

		to ensure all metrics have been retrieved. This is not necessary for 

		RFbsGlyphMetricsArray.

	4. Measure time between first and last font/loop.

	5. Destroy test fonts so that next test has to re-rasterize the glyphs.	

@SYMTestExpectedResults

Since this test uses non-rasterized fonts, RFbsGlyphMetricsArray should be faster than

GetCharacterData() and RFbsGlyphDataIterator, which both rasterize the glyphs in order to 

get their metrics information.

Measures the performance of querying the TOpenFontCharMetrics using the different

available APIs. RFbsGlyphMetricsArray, RFbsGlyphDataIterator, and CFont::GetCharacterData()

are compared against each other, using the same fonts, and same sample data.

This test uses glyphs that have already been rasterized, thereby possibly reducing the 

extra overhead this has.

@SYMTestActions

i. Load sample text data from config file.

ii. Create test font.

iii. Pre-rasterize glyphs using RFbsGlyphDataIterator. This will rasterize the glyphs 

	and cause them to be cached for use by all the APIs tested here.

iv. For each of RFbsGlyphMetricsArray, RFbsGlyphDataIterator, and CFont::GetCharacterData():

	1. Begin the loop, calling the necessary API once per font/loop.

	2. For each glyph, request the glyph metrics.

	3. Measure time between first and last font/loop.
