Noel c7483d48df drop operator bool and operator! from Bitmap and BitmapEx 
IRC chat:
<quikee[m]> noelgrandin: doesn't adding operator bool to Bitmap
  has the same problem as Graphic and the reason why you dropped that
  commit 7334034ae9
  "drop Graphic::operator bool"
<noelgrandin> quikee[m], hmmm, good point
<noelgrandin> maybe I should just drop both operator bool and
  operator! in favor of IsEmpty
<quikee[m]> noelgrandin: I don't remember what the problem is I just
  remembered we dropped it Graphic :) sure, dropping everything for
  IsEmpty is probably the best

README.md

Filter registration and some simple filters (also descriptions).

Desperate splitting of code into small shared libraries for historical reasons presumably (OS/2 and Windows 3.x). The libraries produced from the code in each subdirectory of filter/source/graphicfilter are graphic format import or export filters. But they don't have uniform API. Some have either a GraphicImport or GraphicExport entry point, and are loaded and used in a uniform fashion from code in svtools/source/filter/filter.cxx. Others have different API and are loaded from other places. For instance "icgm" has ImportCGM, and is loaded and used by sd/source/filter/cgm/sdcgmfilter.cxx (!). Svgreader is used for "File->Open" and then to choose the svg file. For "Insert->Picture->From File", see svgio/source/svgreader directory.

==================== filter configuration

The filter configuration consists of two parts, the type definition in filter/source/config/fragments/types/ and the actual filter definition in filter/source/config/fragments/filters/.

Each file type e.g. text file should be represented by exactly one type definition. This type can then be referenced by several different filters, e.g. calc text, writer text.
