Define behaviors of FPDF_RenderPageBitmap_Retail and FPDF_FFLDraw.chromium/2858chromium/2857chromium/2856
Previously, PDFium only supported widget annotations to draw forms. As
we've implemented other annotations, the behavior of
FPDF_RenderPageBitmap_Retail and FPDF_FFLDraw changed. So, this CL
clearly defines what needs to be done in FPDF_RenderPageBitmap_Retail
and FPDF_FFLDraw.
This CL first assumes that PDFium users will always call
FPDF_RenderPageBitmap_Retail and FPDF_FFLDraw to render PDF pages,
because otherwise they are not able to support PDF forms.
FPDF_RenderPageBitmap_Retail should only deal with non-widget
annotations, such as highlight, underline, text, etc. If
FPDF_ANNOT flag is passed, non-widget annotations are drawn. Otherwise,
they are hidden.
FPDF_FFLDraw should only deal with annotations that requires
user-interaction, such as widget annotations and popup annotation. Since
popup annotation is associated with non-widget annotation, they should
not be drawn if the associated annotation is hidden. Thus, if FPDF_ANNOT
flag is passed, popup annotations are drawn. Otherwise, they are hidden.
Widget annotations should be always drawn regardless of FPDF_ANNOT flag
since they need to be always displayed for PDF forms.
Also, roll DEPS for testing/corpus to 8485b30.
