Loads a bitmap from a file or resource, putting the resulting data into
@a bitmap.
+ @note Under MSW, when loading a bitmap from resources (i.e. using @c
+ wxBITMAP_TYPE_BMP_RESOURCE as @a type), the light grey colour is
+ considered to be transparent, for historical reasons. If you want
+ to handle the light grey pixels normally instead, call
+ SetMask(NULL) after loading the bitmap.

@param bitmap
The bitmap object which is to be affected by this operation.
@param name
If you need direct access the bitmap data instead going through
drawing to it using wxMemoryDC you need to use the wxPixelData
class (either wxNativePixelData for RGB bitmaps or wxAlphaPixelData
- for bitmaps with an additionaly alpha channel).
+ for bitmaps with an additionally alpha channel).
Note that many wxBitmap functions take a @e type parameter, which is a
value of the ::wxBitmapType enumeration.
In wxPerl use Wx::Bitmap->newFromBits(bits, width, height, depth).
